This is the thread I read that describes my issue. I am sorry if there is one that I could not find to reply to , so I am pasting it here.
Hi, this is a gamebreaking bug that completly destroys inmersion but also affects singleplayer users, if you save an skirmish game after you produce some units , when you load the save back the building will no longer produce, it will put the units at production line but it will never produce them, the time of the unit production keeps completly stale.
HOW TO REPRODUCE:
1- Create an skirmish game
2- produce some units
3- you must NOT let all units be produced, put three units for example in production line, await one to be produced and then pause the game.
4- you must be in pause menu now since you followed the other step, now save the game
5- exit the skirmish game
6- load again
note: i dont know if it has something to do with imperial age type building, i think not
This bug is showcased in season 5 PUP , and live game, i have examples for both.
SEASON 5 SHOWCASE OF THE BUG :
SEASON 4 LIVE GAME SHOWCASE:
note: this time is with the ottoman civ and its using the military schools but the premise is the same
Best regards, hope it will be fixed soon, its actually a massive bug.
