Mapper Problem with empty house palette

Hello, ive got some map/editor issue and need someones help, so:

I have deleted manually all houses by the map editor in house palette (i am using offical otservbr map + some custom edits without touching rl stuff), i tried to copy old house.xml to bring back houses, but it doesnt work, i imported one map to another one, and in editor it worked fine i had actual map + houses, but when i saved it and uploaded to server or tried to reopen it house palette was blank again, map was correct. Aswell after the save, house.xml was correct, had all houses needed but for some reason these 2 files doesnt cooperate. Would you be able to help me with that? ofc as paid job

If anyone can help me, please reach me out on private message

Houses need 2 things.

1 - The house.xml file with all data for each house


2 - The map with all the houses painted AND the exit in the same position as in house.xml

Point 2 is most likely what is failing for you.
