I Know this is well reported. Hopefully this is specific detail that will help fix. I have repeated this with backed up saves on my last scavenger bot to be sure.
When playing the prologue chapter while a scavenger bot is look for respurces.
- What did you do before you experienced the Bug (please be as detailed as possible)?
If you play the prologue mission in either coop or single player while a scavenger bot is looking for resources then that bot will be lost.
I have repeated thsi from both a saved checkpoint mid game and from dropping a bot in the weapons arena. Then starting the prologue chapter.
- What did you expect to happen?
I expect my inventory to persist and my scavenger bot to be available.
I have paid for the bot DLC so am particulary upset to be reduced to only one bot, or the option of having to play through from scratch.
