I'm wondering if anyone can help me with this rather annoying problem. I recently started adding lights to my map (up until then everything had the unnatural glow) though I did not add light to everywhere on the map (that needed it) - just a couple of places to test out how the lighting looked in those places. I compiled the map, and it all ran fine. I then added more lights and started getting problems with it crashing, so I followed the advice on this page ([INFO] How to make a complex map not entity CRASH!) but nothing has worked. Now when ever I try to compile and run the map I am always get the "error! reliable snapshot overflow" message. In order to try and reduce things, I have removed all the lights from the map as well as turning everything that is not already one type of entity into a func_detail, but still with no difference in the outcome. FYI, my point entities count is 556 while my solid entities count is 592, making a total of 1,140. I have included my log file, but as this is my first map I am still new to understanding what it all means - http://dl.dropbox.com/u/8368863/Factory%20Backups/achievement_factory_rc3.log If anyone can point me in the right direction or advise me on the probable reason for this error I would be most grateful!
