Epic War Age (EWA) - Adapted Mod Collection

On version 2.7.1, I completed all the original campaigns plus several custom scenarios. If there were any crashes, they were so rare that I can't recall any now. The only problem was that I sometimes had to disable Eternal Essence and MegaAI to make the scenario work in the campaign. I also further customized the build for myself with mods for visuals, balance adjustments, and a reshade. Overall, there were no problems – everything worked perfectly. I'm saying all this because the problems are likely more related to the system on which it's running than to the build itself. Try patching the executable file to allow it to use more than 2GB of RAM and update all system packages/libraries.
