Game Freeze problem.

I have some serious bug in pyramidal defence.

At some point game simply freezes.
What is most annoying is that I cannot debug it.
It freezes and when I turn on task manager I see wc3 is using 99% CPU and that it allocates memory like crazy.

Any ideas in witch direction to look?

It's probably something to do with your system/s. I'd check out your data system first.

Don't think so, they have been heavily tested and all have debug mechanisms.

Well, then that's off the list then. Go brute force and check each one of your systems. I doubt the problem has to do with anything else than code.

Also, try to find out when the map usually starts to freeze, then check what could be the problem by investigating that environment.

See that is exactly the problem I cannot save the fucking replay because the game freezes, and I have no idea why it happens.

Then you'll have to do it the hard way. Play it and try to make it freeze, carefully being on the lookout for things which could be the source of it.

I'd try to force-freeze it if I were in your shoes to find out the possible causes.

Well that is exactly what I tried to ask here, how do I force the map to freeze?

You actually asked where to look.

Anywho, when was the last time it froze? Can you recall what the hell was happening and what were you doing? What was happening in the game?

Dunno, it never happened because I did something.
I just stood there and the game frezes, I guess someone else casted something or it was a combo of spell that mixed up...
But I cannot see what it was because the game freezes and I cant even move my screen...

Something probably reached/went over the OP limit, maybe an endless loop.

Infinite loop of some kind is most likely cause.

But op limits don't halt game?
Or does grimoire prevent that?

Can I play on BNET with grimoire turned on?

An infinite loop halts the game.

Grimoire amplifies bugs, mainly with infinite loops, so you should try to catch them without grimoire by adding a custom checker.

What the hell is a custom checker?
