Once again, my title says it.
Any way I spend those 5 seconds, it always freezes, and I have to go to Windows Task Manager to close Battlefront down.

The problem is, I have no clue what the problem is, so could someone help me diagnose the error?

The only unusual errors in the error log deal with leaftrees (which by the way are having problems with the leaves and displaying a textureless square for each attached leafclump, even though I have all the odf's and msh's)
Also, I think there might be something wrong with one of my memorypools in my lua, whether it be too high or too low.

So here's my LUA:

The leaf trees don't crash a map, or freeze it. Also, are any of the units custom or are there vehicles placed in the ZE? I had a problem like this and it was due to an error with a weapon. The map would freeze, and I would have to do what you're doing. It is probably some type of error whenever a unit shoots. That was what happened to me, so you could eliminate all bots and then just go through with each character until it freezes, then you know which weapon.

Those errors you posted aren't unusual errors; they'll happen in any map where you have multiple of the same kind of object. You can ignore them.

And re: crash/freeze - things rarely "wait" to react badly. If you're getting an error 5 seconds into the map, it means that something's happening/being loaded/spawning at that time that's causing an error. Usually this'll be the result of a unit with bad .odf properties set up. Check them out.

Hm, that's strange, because I have no custom sides, vehicles, etc. at all.
No vehicle spawns either.

I had that happen to me with Concord Dawn. It ended up that one of the AT-AT props I was using had an odf that pointed to a missing msh. As soon as it came into the field of view of a unit (including AI) the map crashed. Not saying that's it, but it's worth checking into.

Check the ODF for end_prop_treeclump03.

By default, it reads You need to change it to

Yeah I had that problem before, I just deleted all end_prop_treeclump03 objects from my map and replaced them with end_prop_treeclump02.

And unlike this problem, it showed up in the error log.

So there's nothing wrong with the memory pools?
I'm particularly concerned with the TreeGridStack pool size. None of the stock maps have a TreeGridStack memory pool anywhere near this huge, but the error log had told me to set it to at least 1430.
Yavin and Dogabah have them at 500 and 200, respectively

And the leaves still don't show up properly

lol I had that problem with Haruun Kal. Basically as far as leaves go you have way to many trees. I think I ended up dropping the amount I had to ~1000 before I could see the leaves while on foot, and ~900 to see them on the trees while in a flyer. Unfortunately there's no memory pool for the leaves, it's just a hard coded max.
