I'm sorry to come here again, but I ran into an annoying bug that caused me to debug my entire modpack. All I did was adding following entry (without having it used by any weapon/ship) to the tbl:
$Effect: Firespew
$Type: Cone
+Filename: ParticleSmoke01
+Size: (50)
+Lifetime: (10)
+Deviation: 0
+Velocity: (10 30)
+Number: (1)
+Direction: Reverse
+Duration: (1)
+Effects Per Second: 2
The result of this was that debug builts (both FRED and FS2, using the recentmost nightly - 20190514 and your SMAA builts) would no longer start but crash with the error message attached below; which occured immediatly after the preload screen. I checked the wiki to make sure everything was configured correctly. No trace of the cause was left in the debug log. It didn't cause any issues on regular builts, and the effect was working as intended.
