Running this buld: https://forums.elementalgame.com/415570 but issue occured before/after switching to it

Later in the game with a lot of units moving, hitting end turn or moving a stack of units causes a very loud, very painful repeating sound - it sounds like the 'BONG' of end turn/units completing movement or whatever, overlapping itself repeatedly until its loud enough to make my speakers crack.

edit: this also appears to be happening to overland autoresolve battles, again, overlapping the fighting noises extremely loudly
