Oh, and in addition to my posted mantis bug #0852, I can partially reproduce it now (since it happens everytime again when I rebuild that mission).
Unlike my other missions, this is the first time I use transports with docked container, so maybe there is something wrong with the docking-code, but that's just for information what I did different in this mission.
However, I figured out two situations where these white textblocks appear.
1) I place so many highpoly ships that I ran out of system-memory
2) I place a model in a large distance away from the mission-area center, in my example + 50.000 units on the z-axis.
Now, I really fear to ask, but have you people changed/reduced the size of the mission-area ? I sincerly hope not
