Hey guys Dev here!
We've just pushed an update to fix the map issues from UI scaling in the last patch. I'm sorry about the trouble its caused.
If you are still seeing some misplaced explored regions on your map, they are due to areas that may have been explored during the 1.1.79 patch. All of the exploring done before and after 1.1.79 should behave as intended!
Thanks everyone for vigilantly reporting bugs! please dont hesitate to let us know!
