Like the topic title suggests this is still happening in Tarkov (Patch .9)... I know boiler tanks is a crap fest but really this isn't something that couldn't be easily remedied by lowering the amount of max players on Customs or moving some spawns around. I thought the idea of getting rid of the option to choose your spawn location was to fix this.

Yeah I thought this was fixed a long time ago but at this point, I feel like the devs are disabling and re-enabling these bugs every other patch just to mess with us lol
