In a gambit match on the emerald coast once the third wave was defeated and no new wave spawned. The icon that displays where the location of the enemy wave was stuck in the same place and no enemies where present on the map. The enemy team was still progressing and the only AI that would spawn would be blockers. My team could not collect motes as no enemies spawned. It eventually spawned a new wave when a "catch-up" HVT spawned and was defeated but by that point the enemy team had defeated their primeval. This only occurred once during my time playing gambit this season so I am unsure of the bug's frequency. I also don't know what circumstances might have caused this to happen so I apologize for lack of detail that could help resolve this issue. There was no AI that my team missed or present on the radar before the HVT spawned so I'm pretty sure it was not my team's failure to complete the wave. I hope this brings attention to pretty nasty bug and any effort to that is made to address it is appreciated.
