for some reason i still don't have access to the swamp area even though im level 15 almost and on day 50+ I even rescued Flo already, how tf do I unlock the lizard village, I killed him and showed his guts to the bull chief, and now Thane is forever stuck asking me to wait a second because hes cooking.

the lizard village itself is one of the first things you can unlock, you should have met Nauxus, who taught you how to tease, then you can go south and explore a few times, should unlock a spot more west, Nauxus is there, and will bring you to the village after the spy quest

If you haven't checked this part of the map, you need to explore it 3 times, and press yes to meet Nauxus. He will invite you to the lizards' village where you can progress. (Activate windows watermarks are funny.)

Otherwise, that save file is likely corrupted. If you run into any story troubles, Redyoshi's guide is pinned on the community posts, and it is the guide I use for my playthroughs. If any issues outside of this happens, you may want to contact a mod.
