oO both demos desync for me... some stale files or sth. like that?

releated because of me. i don't trust my own reports... side note: validation client runs on the same computer. so a verification from someone else would be great.

 i made a diff with demotool -d of both demos:

the only real difference i find is this at the very beginning:

-00001 SYSTEMMSG: Player: 255 Msg: -> Address: [127.0.0.1]:57269

this line is only in one demofile. is SYSTEMMSG synced? + could it be the cause for a desync? if so, i would expect a desync a few frames after this then.

yes, but clients only print it to console

when running the demo(s) I'm synced with the client and not with the server.

probably also the result of ownerExpAccWeight being uninitialized

Unlikely, as the map has no water and I think only torpedo weapons had this issue.

BA has depthcharge turrets (that tend to get built by AI's), which are TorpedoLaunchers.

 need to check if any of these were built in the demo then.

EDIT: just checked, none were built.

it seems at least mines/corsktl and armvader were affected, too.

nothing synced was supposed to be changed unless a unit hits another unit.
in this game no one fired IIRC.

last "new" unit which was build in this replay before the desync was a cloak tower... but it wasn't finished: so not sure if relevant.

hm, valgrind finds some stuff with this demo.
i try current development version with some test game and with -fsanitize=undefined and when i find time with valgrind, too.
