Thanks to Miloch, one of my MegaMod Mercenaries, the crash in ARPO28 has been fixed once and for all.
Unzip and drop the WED file into your override folder. Should work with any version of TDD created and the crash was a sort of random thing so everyone may not have experienced it.
This will be included in TDD 1.14 and that will be ready when the current translation (Spanish) is completed. Should be about a week.
