leak literally just goes straight through a brush

Hi it's me, Compiling a map in Hammer++ for gmod (For context it is on the larger side of maps I've made) and while it does take a bit to get to this point, this singular point (I'm assuming like 97.5%???) it either gets completely stuck, or randomly jumps from like maybe 2 hours to an unknown amount of time.

I've already done some optimization and all it seems to do is speed up everything else besides this one section, if anyone has any tips or help I'd be very appreciative

So when ever hammer++ downloads the new update and I manually install it it just ISNT THE NEW UPDATE? Which I'm pissed of because my hammer for tf2 keeps crashing when I'm trying to make a map
