So I add a custom region, turn it on in a remix, new rooms appear on the map, I reach the gate to a new region, the first door closes behind me, the second door does not open, leaving me locked. This happened with two regions: Coral Caves and Pilgrim's Ascent. I included everything that was needed in the description of the mods, and I also did not have anything extra (except for the remix, msc, jolly and expedition). I'm not very good at all this, can anyone tell me what could be the reason, please?
