To whom it may concern @DE, Naeglar is one of my favourite missions and I try to do a couple of runs a day at least for the cache rewards (Mods, Endo and Co-ordinates) but there is a serious bug on this map which forces mission abortions.
After destroying all five tumors one of the hives may become invincible. Any time spent, sculptures found or caches opened at that point go to waste leaving me feeling quite salty. This bug has existed for some time and I would ask that you look at the relative mission abortion rate compared to any other sabotage mission and I am sure you will spot a statistical anomaly caused by people like myself who begrudgingly abort about one in five missions due to this bug.
Can you please look into this?
EDIT: If anyone has found a way to complete the mission successfully once a hive has glitched please I would love to know
