When in werewolf form, the prompt to 'hold F to resurrect' another player appears as normal, but holding F neither plays the animation nor performs the revival, regardless of how long you hold it. After transforming back into human form (whether manually or by running out of time) it behaves as normal. So far I have reproduced this 100% in multiple environments (dungeons, overworld etc.) and two of my friends both have the same issue. If it helps, we're all on PC, European server.
This has massive impacts on playing a werewolf in a group particularly in dungeons, and in particular it directly contradicts the 'pack mentality' design theme of the werewolves by making it unfeasible for an all-werewolf group to play through dungeons. If this is somehow intended, I feel it makes very little sense as a design decision and makes the werewolf feel extremely clunky and unreliable. It's also very confusing that the prompt still appears, as the first time I encountered this issue I attempted to resurrect for a very long time, thinking I was somehow messing up my inputs. Although I'd much rather see werewolves be able to resurrect, at the very least the prompt should not be appearing erroneously. Finally, I feel that a fix to this issue would have negligible impacts on the actual balance of werewolf transformation, and would purely be a quality of life change (e.g. this isn't going to make werewolves suddenly OP or anything).
Hopefully this can get fixed soon! This bug aside, playing as a pack of werewolves has been great fun so far
