Lost my last unlock.
I was playing in a dueling server, trying to get to the Thrusting Dagger.
I managed it after a bit of playing, and used it for a bit. Then the map shifted.
I now don’t have my thrusting dagger anymore, and all the kills i got on my crossbow were also reset to a previous state.
I have the achievment to prove I unlocked it… what do I do?
Restart the game and/or Steam. Unfortunately right now, thanks to the free weekend, there is a bug messing with ranks and weapon unlocks. However, it does save to Steam Cloud so just restart.
