Describe the bug
A clear and concise description of what the bug is. i was in an apartment tower on the 2nd floor when i found a mobile generator. for some stupid reason i decided to drag it to a nearby balcony and push it off, the game then gave me a bug report which i ignored and my game became extremely slow it took about 5 seconds for a turn to register. there was sound coming from below the ledge so i went down the stairs then the game became so slow it now takes around 20 seconds for a turn to register and i had to mute the game because each time a turn passes i hear 100 crashes that are insanely loud. i approached the still partially intact generator to see whats happening and then dragged it to see if it would fix but it didn't To Reproduce
try pushing a vehicle off a ledge

i destroyed the generator and it crashed my game

I was able to confirm this issue. Pushing a cart off a ledge causes the game to really chug. It does not like that one bit.

I'm unable to reproduce with the latest build. Anyone confirm this still exists?

EDIT: Got it. I needed to enable 3d fov and once i went downstairs to check it out everything was very unhappy. Then disabling 3d fov seems to return things back to normal.

Still a bug, but I've given up on getting 3D vision option totally stable for 0.E, so this isn't a blocker.

i think i found an easy way to reproduce this issue.

Get on a rooftop with a drainpipe (the tile you can use to climb onto & down from roofs)
Spawn in a shopping cart
Push the cart onto the drain pipe
It should start slowing down and spamming the you hear a crash message

I am pretty sure this bug is the result of a falling vehicle not having a suitable empty location to land. And since it keeps trying (map::vehmove), vehicle::slowdown() is constantly called and ends up with that overflow.
