Oh, I was playing the Enif Station mission, and i lost the station about 5 times! Since when did the cruiser assulting the station have green beams?!? It destroyed the transport in a single hit, and Enif Station in about 3! I found it nearly impossible to save Enif station. I finally finished it on Very Easy (I played it on Hard, then Medium, then Easy, and finally Very Easy) after Enif Station was down by 5%! I lost the transport, too!
This shouldn't be happening. The Cato's SGreen should only be able to damage the freighter on Medium, and it should not really be capable of destroying the station in three hits. Sounds like you've got some buggery table running around somewhere or some rogue mission file. The only ship that should be doing that much damage to the station is the corvette that shows up once the Cato's been destroyed.
I know it shouldn't be happening. The Cato's SGreen seems to be updated signifigantly.
I have loaded part of the FSO 3.6.9 files... I am awaiting a few of them, but I have the first 4 or so in. This is the first time it has been so buggy.
I don't think I have any tables that edit ships that way. Maybe a rogue file overwriting the OEM Cato with a FSO Cato.
The mission became very glitchy, though there is no logical reason for it to become glitchy! The glitches went on

. The Cato destroyed the first transport (should have been impossible for the Cato, as the transport has quite a few lines to say before a possible explosion. I lost it about 3 seconds into the mission, and saw ghost lines from the nonexistant ship. It was only when that transport was taken out that I could destroy the beam on the Cato. There was absolutely impossible to prevent such damage to Enif Station. You are about two clicks from the Cato. I replayed the mission a few times, trying different things. I restarted, and once I saw a image i held tab to use afterburner. I boosted engines to 100% of energy, and put throttle at full. I got my harpoons out and targeted the Cato's beam (default target) in double-fire mode! I fired about seven times until it was at 0%! I actually disabled the main beam on the Cato a few times, losing the station to secondary firing (missiles and turrets). I lost it about two times to secondary firing, and about twice to bombers. I nearly lost it to the Corvette that jumps in.
I remember that I was able to progress in the mission after Enif Station was disabled to the point that bombers continued to jump in, and be destroyed. I got three wings of bombers after Enif Station was destroyed. The Cato was destroyed, and then the corvette jumped in. A few more wings came at me, and I was able to destroy them. The Colossus never jumped in, and the corvette left. About two more wings came at me after the Corvette left. I had two red events... Protect Enif Station and Destroy the Manheim (or something like that for the corvette's name).
I remember that it was nearly impossible NOT to destroy the Cato single-handedly. I have played it a few times having fun with the Cato...
My favorite thing to do in this mission is...
Tell everyone to ignore the Cato. Use my Stiletto II missile and disable the beam weaponry. Use the Subsys disrupter to take out the subsystems. Restock Stilettos and continue till every weapon and subsystem on the Cato is been disabled.
Thus, the Cato is now disabled and disarmed. The ship is in the middle of the battle, with nothing touching it. I tell the transport to capture the Cato (which ends in the transport taking 5 minutes to move into position. They dock, and refuse to undock until the Cato is destroyed. Usually, at this time, my order seems to expire, and Enif Station fires upon the transport blocking the Cato. Enif Station never falls below 58% on hard mode while I do this.
It's weird... I have never seen an assult cruiser destroy the Transport AND Enif Station. The transport took less then one hit (the beam was active for a while after destruction), and Enif Station took three or four hits before it too was destroyed.
It should be impossible to lose the transport seconds into the mission, and/or to have the destruction of Enif Station due to the assult cruiser. Both have many lines into the mission that ghost after their destruction.
