If people are still experiencing issues, we need to know:
1) does it crash outright, or is it a freeze(non-responsive hang)? (if it crashes, can you send your crash report (zipped) to cameron (at) beamdog.com) 2) what were you doing when it crashed/froze? 3) can you easily reproduce it, or was it a one-off thing? Timing, like every X minutes, or usually when performing Y action? Anything that makes a pattern so we can try and reproduce it on our end. 4) does the issue occur in a non-modded/brand new playthrough?
These are things that will help us isolate and try to reproduce the issue so we can fix it.
we're currently digging through multiplayer in an effort to provide a patch soon(tm) (read: as soon as we can) to fix a lot of the issues people are experiencing.
-We've currently identified an issue where the legacy code/missing rest movies causes big problems for people - copying the existing rest movie again to restinn.wbm and restdung.wbm in the override fixes the issue, so, that's what we'll be doing in an upcoming patch to "stop-gap" the problem, and then replacing those duplicate rest movies with something better in the vein of the existing rest movie (but area appropriate) going forward.
-likewise, this may be related to other multiplayer weirdness when playing other movies (again, the ghost of the legacy code causing problems),
-there's at least one general connection issue reported here that we'll be looking into,
-we've also identified many people are experiencing general instability with 3 or more people in-game (but 2 seems to work fine for most people), along with some specifics as linked here (1), here (2), and here (3) with some workarounds there too.
Now: the reason why I'm posting that here is, as the last few links above there, the specifics listed are very good. If anyone can provide us with more tight reproducible cases, the faster we'll be able to squash the bugs in question.
Cheers - this topic will be updated with more information as we identify specific issues we discover or other cases people can point us at to fix.
