was this in the team aakas? as i thought it was changed to lootable mobs with no chests on solo runs, or is there an advantage to chests like greater chance of rare loot?
i had an issue on aakas 4 solo back in august, where a gate just before the mid boss wouldn't open, ended up using all 4 attempts and it never opened. I made a post on Ark forum, which devs ignored/didn't see and contacted support with no response at all. Fortunately, as the mobs dropped loot i was able to cover my costs.
hope you can get it sorted, i stopped running the aakas due to my issue and it shows there is multiple bugs lurking in there
