Ok so I just did 2 runs to test if/how claymore's are the G_spawn issue, the first run I placed 44, then before I could place another one the map crashed and I got a G_spawn error, these claymore's were in tight bundles randomly placed. The second run I placed 55 (ish) before the map crashed however these ones were more-so inside of eachother (about 10 placed as close to the same way and same spot as possible.) It could either be:

1. % of claymore/entity coverage over the map (possibly)
2. exact amount of claymore's on map (very unlikely, I would have only miscounted 1-2 claymores)
3. after X claymore's the map will crash after X seconds
4. after X claymore's placing X more in X seconds will get an error

Please note though, I did all of these solo on round 2 with only the doors to claymore's open (only had starting pistol), no cheats enabled, all but 1 claymore's were spawned in using the dolphin dive glitch, no zombies killed after I placed first claymore.

Me and my friends were playing this map the other day and we kept getting a 'g_spawn no free entities' error for some reason, the first time we figured it was due to too many 'glitched in' claymores and said we wouldn't do it anymore but the second time we went quite a few rounds without anyone doing the claymore glitch (as far as I know anyway) and then we got the error again, what else could be causing this issue?

Also great map guys, really good quality and one of the few maps I enjoy replaying.
