Had this just happen in Cavia Exterminate bounty with Lohk Surges.
While no logs were requested, I uploaded my EE.log as ticket #3447191
While playing a Cavia Exterminate bounty requiring 3 Lohk Surge activations, the game bugged and we were unable to complete the bounty.
In this instance, there were two Lohks Surges in one room. I activated both (and the HUD reflected 2/3 progress). However, 5-10 seconds after the second activation, a host migration occurred when the host left or crashed. When the mission resumed, it now showed only 1/3 progress.
We continued with the mission until we found the third Lohk Surge. Upon activation, however, the HUD still showed only 1/3 progress. After playing around for a while, I went back and re-activated the first two Surges; however, the Lohk Surges provided no buff, gave no mission credit, had NO visible cooldown timer, nor could they still be activated. Eventually, everyone aborted and failed the mission.
