Random drops from the battlescape to the geoscape with error:
ERROR: LE_DoEndPathMove: Actor movement is out of sync: 158:139:0 should be 159:140:0 (step 1 of 1) (team 1)

It happens randomly when moving soldiers. I've not found any consistent conditions causing this error, but I know it can happen even when moving in straight line, no obstacles, no aliens or civilians nearby.
Some maps seem to make this error show more often (don't know "internal" map names): asian pagoda-like with a harvester; small, narrow in a africa map with simple huts, a small hill and a harvester, other maps too.

Win32 build 29356 http://ufoai.ninex.info/forum/index.php?topic=2830.msg36575#msg36575 but it happened in previous builds too.

VERY annoying :(

I had this same crash happen to me on a medium oriental map. From what I can see in the ufoconsole, it loaded the following map artifacts:

CM_LoadMap: "-oriental/or_ +craft_drop_firebird +house_b +house_c +house_e +house_f +craft_crash_fighter +house_a +house_b +well +well +trees_a +trees_a +stand_b +trees_b +trees_a +trees_a" "-24 16 0 8 -24 0 0 8 0 8 -8 0 -24 0 0 -16 -24 0 -8 0 0 0 16 0 -8 8 0 16 -24 0 16 8 0 -24 -8 0 -24 -16 0 16 16 0 16 24 0 -24 -24 0"

I have also seen this crash happen on a previous build when one of my soldiers killed an alien. In that instance the game crashed when the alien died, but nobody was moving. Unfortunately, no console log of that event.

please be as detailed as possible what your last action was.

Another "fresh" example: moving soldier to adjacent square, soldier was looking in another direction. A few turns of fight before that.
Sometimes, all preceding actions made with a soldier that caused this bugs are movement only (like moving all soldiers towards the ufo, when I know that all aliens are inside and I just rush).
I've not managed to get inside the ufo on the asian "pagoda" with map the harvester (5 tries or more). I if find a savegame that causes this bug often, I'll post it here.
====== tlh2000 (2010-04-25 12:29:20) ======

that bug isn't savegame related - it's related to the last performed actions you did on the battlescape. was your actor crouched? was someone dying? shooting? whatever - your events.log might be interesting, too
====== tlh2000 (2010-04-25 12:30:20) ======

to activate event logging set the cvar

cl_log_battlescape_events

to 1 (game console => shift+esc => cl_log_battlescape_events 1)
====== morkil (2010-04-27 20:28:45) ======

events.log and ufoconsole.log
====== morkil (2010-04-27 20:33:34) ======

Ok, this time I was prepared, got one ;) A soldier stepped in/on a right harvester wing, logs in the attachment "morkil_crash_1_29523.zip". I can send stats.log too, but it doesn't have any timestamps, so i don't know which lines are corresponding to the current battle.
