Just posting this here incase anyone was having this problem. So with Dragonborn I suddenly was having my log spammed by the critterspawn..and scripts that inherit it. So, I believe I found a bug. Not only that, actual ingame models(bugs, fish) had began multiplying at a rapid pace in the Raven Rock area, causing stutter, and bloating my save endlessly.

The fix is in the SpawnCritter() function. In the original script the else condition did not have a return value. This was a problem because the function expects a boolean returned. Instead Bethesda did some odd thing by setting a variable instead of simply returning false as well. So i inserted a 'return false'. This seemed to have fixed the endless loop the script was stuck in.

Hopefully it eliminates the bloat..initial testing has been positive. Did not see log spamming using a recent save. If anyone wants to test let me know how it turns out, please use a 'test' save if you do.
