I installed Tot initially on Windows 10, following the instructions found here: http://users.tpg.com.au/jpwbeest/cc_tot_install.htm TOTP told me it could not run "civ.exe" and I could not even run the game (I got an inf it will not work with this version of WIndows) unless I replaced the original civ2.exe with the one found in nolimitstot patch. With this, the TOTP work and the game starte. I had no problems for a while. But finally, in the end of one turn the program crashed. No problem, I restarted, but it keeps on crashing in the exactly the same moment. I put my save here: https://nofile.io/f/GV5pXw9crYv/al_a1330.sav Just move the settler and the turn ends. Siouxes start to attack and this is when the game crashes. I run virtual machines with Win7 32 bit, then with WinXPsp2 and everywhere it is still the same. It crashes in the same moment. What could be the cause? Any idea how to fix it?
