Actually I have a problem with this as well. Making complex, heavily jeweled ships at some point causes the same problem for me. I wonder if there is a graphical limit with the graphica engine or whatever such. I have TA 2.01 currently, and still have this problem. I think my DA games also had this problem.
Is this a hard coded problem issue or such? Or is there a link to read about all this? Kinda would like to know myself here. Any answers are thanked in advance. =^^=
