I created a map with Photoshop that should meet the requirements of Loathing - it's 1280 by 1280 pixels, 72 ppi, indexed color with 240 colors, and the first time I tried it with Loathing it loaded up fine. I did some terrain, raised the map edges, limited the view to 25, etc., just basic stuff, and then saved it. The next time -- every time -- I try to load it with Loathing, the program quits. The only thing different is that I put some landscape objects and units in folders within my local folder that I'd meant to use.
I've tried this both on my G3 powerbook with 64M RAM and with my iMac with 96M, both with and without virtual memory.
I'd be grateful for any advice, posted here or to rpklc@etal.uri.edu.
