Drizzle has a part on the "Misc" tab called "Run Tests" which will try to find sequence prefix conflicts. It can sometimes be helpful! And yeah, this has sometimes happened before when someone creates their own Age (or installs an Age not from UAM) which uses a prefix in use elsewhere. (I'm not saying that's what happened here, but it might be related.)

No problem; don't worry :)
(I prefer email to forums anyway. Sometimes I go several days without reading the forums.)

I had the same problem with several Ages failing to load, giving me a black screen like that.
I suspected corrupt files because Ihave been doing lots of tests lately.
I ran the Dizzle tests as mentioned, and the log ended like this:
- Show Spoiler
Code: Select all

I guessed that Fens was OK and the crash happened on the next file, so I looked in my dat folder, sorted alphabetically, to see what came after "Fens", and found a corrupt prp file.
Deleting that file solved the problem.
Dustin, thanks for those tests. However, maybe you should trap errors so that the test won't crash? So that it processes all prps.

Yes, that could be done. Sometimes getting the stacktrace is more useful though, because it can point out precisely what the problem is.
