are you sure the crash is happening when clockworks attack?
As I can see on the error, the crash is happening when clockworks dies and are support to drop items..
too many items drops at the same time?
too high droprate?
yes sir i'm pretty sure if i kill it first before it attacks i can loot it's drops but when it attacks the world dont responds anymore then closes and gives dmp/rpt/txt errors :/
perhaps than doubt check everything to do with the monster, I won't bother with everything because clearly he can spawn and move at least from the sounds of it, so either an item is causing the problem as stated above by "Xakzi" or an attack animation is missing?
PropMover.txt
check for in proitems.txt/Spec_items.txt and defineitem.h
II_WEA_MOB_CLOCKWORK_ATK1
II_WEA_MOB_CLOCKWORK_ATK2
II_WEA_MOB_CLOCKWORK_ATK3
II_WEA_MOB_CLOCKWORK_ATK4
check animations
mvr_ClockWork.o3d
mvr_ClockWork_atk1.ani
and so forth....
Also look over the
PropMoverEX.inc seach "MI_CLOCKWORK1"
Perhaps an item within the loot table as suggested is causing the crash, maybe it's not dropping all the time.
I believe mine is a V15 propmover.txt and I've not bother upgrading the source that much in the time I've messed about with it, I doubt that is the cause to be blunt, however it might depend on if that's the original propmover or one you've taken from another source without upgrading the source to handle the three new rows?
katchup did suggest running it in debug that might be the best option for you i wish you luck, I'm not a coder so I can only give random suggestions on the problems I've had.
