ToME: the Tales of Maj'Eyal

Thanks Moasseman. That triggered a whole lot of exploration unlocks, and the bikining along for exploration was unlocked. But it was not unlocked for other modes. I completed the game in Normal Semi Roguelike (mild), perhaps that does not map to a Steam achievement? Character: https://te4.org/charac...

My lich archmage faithly wore her bikini all game. I did get the Bikining along achievement at end of game (I took a screenshot), but it is not showing in Steam achievements.

Why is that? is there a way to fix it?
Thanks
M
