RoboTank is a tank that drives and shoots automatically, following the lead of a manually piloted commander vehicle.
Mods introducing new content into the game.
New ways to deal with enemies, be it attack or defense.
So I tried adding new mods in game and now my saves just don't load. The problem seems to be coming from the Robo Tank mod as it is trying to apparently rebuild everything and has a memory leak.
Sorry to hear that. Could you post a log file (factorio-current.log) and/or a save game file?
