just use combat with plugins support + HD patch if you want to play campanigns with this plugin.
if you want to play our custom campanigns like Alaunter or Red Mist then not worry, they have save load fix and ai fix by default
so basically you not need gog to play campanigns because gog is shit
and if you want to play multiplayer with saveload fix then its very cursed on gog, you need to have every player with who you plays also get this plugin, otherwise game desync and drop.
you can play on our server easily, just enable rebalanced game mode in lobby, ai fix and saveload fix is set by default, AND its syncronisend by players so game will not drop.
BTW the plugin itself is maked only for singleplayer, its not supported in mp and not expected to even work here at all.
for server side its already here you just play on rebalanced mode or set map with triggers with saveload enabled.
actually lol wtf, is there is even someone who really need save load in multiplayer and also when playing with comps? i can only imagine some super duper ultra hardcore comps map otherwise people basically just play and thats all.
so probably you do not need this plugin for multiplayer at all.
and that means you want it for singleplayer? just use combat for that, gog is shit
