Ns_lemmings Crashes Every Time

Depot

<div class="IPBDescription">Weird error message discovered in log</div> Without fail ns_lemmings crashes, I <i>believe</i> before the game is over (this is an ns map I converted from co_lemmings btw). I discovered this error message in my server log spammed dozens of times and have to wonder if it's related.

It appears these errors begin after alien chambers are built.

Does anyone have a clue what this error message means? Is it map related or plugin related perhaps?

blips are the sprites aliens see on their hud that tell you where the hive/parasited marines are/gorges etc. I don't know what the problem is but maybe that can help you figure it out.

Could the fact that this is a multi-level map re: <b>very</b> tall but square have an effect? If you remember the old missilecommand from 2.0 this is very similar.

Could be something to do with the distance of the other aliens from the chambers or the speed at which they move away from them.
