Hello, I recently acquired a map from a member on my server team that they wanted to add in for a quest. This is an older map from a few years ago (used on eathena) from a server that they used to work on. I can't seem to get it to open in Browedit or add it to my mapcache. I have the gat, gnd, and rsw, not sure why nothing will open it. If anyone has any info or can point me in the right direction on how to get these working, I would appreciate it. Below I have attached the error I get in browedit console and weemapcache
