So I put this here instead of the bug reports thread because I have a theory on why this is happening, I'll probably type in a shorter version inside of the bug report anyways. So this map has 11 randomized perk locations and 11 perks in total which are Quick Revive, Juggernog, Double Tap Root Beer, Speed Cola, PhD Flopper, Stamin Up, Deadshot Daiquiri, Mule Kick, Widows Wine, Zombshell, and Bloodwolf Bite. However, PhD Flopper is in the Zeppelin at the Pack-A-Punch area so that leaves 11 perk locations and only 10 perks, leaving 1 of these locations without a perk machine. Ultimately my guess is just that whenever the time comes for the last location to spawn in, since there are no more new perk machines available the game will try to spawn one in even tho there's no more left and cant handle it so the game just crashes, but that's just my guess. I feel like the best way to fix this is to just add in another perk like Tombstone or something, and it would also be cool to even see a few extra perk locations for some new extra perks like Death Perception, Electric Cherry Elemental Pop, etc... . I thought about this a little bit and I realized with this crash glitch being in the map it would also literally make high round runs impossible so a fix would definitely be great to see!

Edit : I should add in that this has happened to me multiple times as soon as the beginning countdown finishes for the last perk location
