Hi CarolinaReaper4 and rusted_f0rk, thanks for reporting this here on the forums.
It's not something we've come across, so I'd like to investigate further. Can you answer the questions below, to help us narrow this down?
• To be sure I understand: you take out all the enemies at a control point, begin defending, some enemies spawn, but eventually stop spawning while the control point remains untaken, leaving the only option as leaving the control point - is that correct?
• @CarolinaReaper4, did you find this was happening at all CPs, or just specific ones?
• Can either of you get a video across to us showing us this issue?
Thanks so much for your help and patience - we'll hopefully have this solved shortly for you.
