Extracting maps, vmaps, mmaps in Serverside Posted February 28, 2019 First of all, this is not tutorial for any different client version than 3.3.5a (as it is with all my tutorials). I have absolutely no idea how this works on any earlier or later versions and cannot be of any assistance with any issue regarding those versions. Having said that, if you have any issues loading wdt file, clearly, there is some issue with that wdt file. This happens pretty much exclusively only with wdts which are custom or modified. It depends highly on what changes you made to those WDTs and what tools you used on your WDT. I remember having such issues myself, but sadly, I really don't remember how I solved them. Try using different WDT editors, or try creating your own new custom WDT vs copying existing one and just renaming and editing. Something like that SHOULD work. Since it has been 2++years since the last time I updated server side maps, this is pretty much all I can provide and remember.
