I got to stage two and was tasked with killing 15 enemies within the time limit. I got to 13 and realized that the final 2 simply hadn't spawned, then the next conveyor forwards simply would not spawn so I've been stuck on an empty platform for the past 10 minutes. I know I could just log out since this game completely lacks disconnect continuity, but I'd at least like my booster and Extreme Pass refunded.

I know this is a 2 month old thread, but reporting in from PC to let you know the same thing just happened to me and they have not fixed it.

still happening wasted 4-5 extreme passes cuz they just wont spawns owe multiple stages
