Sorry if this has been discussed before, but I used search and didnt see my specific question. Is there a coded limit of map size no larger than 169X121? Ive tried the bigger worlds mod and the unofficial world builder. With some testing of changing the height and width I cant load a larger size than the 169X121. The unofficial world builder has slider up to 256X128, but does that only work for 8 gigs of ram? I have 4 gig and windows 7 64 bit and get an exception dump. Thanks
