Bug with loading scenarios ?

[Lord Sankari]

This is the 2nd time I have to restart a large scale scenario, the one where you play TEC Enclave vs 6 Primary TEC and I don't know if there's a bug regarding the save/load.

Since this is a long scenario, I don't have time to finish it by playing straight 6 hours. So I saved my game several time, and I just realized that loading the scenario makes the objective back to 0 (I have to capture 6 enemy home planets).

The first time I played, I used a bunch of mods, and I finished the scenario by capturing all the home planets. Just to realize that my objective was stuck at 0/6. Nothing happened, all my opponents were defeated on the diplomacy screen, but I couldn't win.

The second time, actually my last attempt, I put away all the mods, and I also verified my files in case of bugs. Nothing was wrong so I played the vanilla version of this scenario. I made sure I was progressing during the game, and yes, after capturing the first home planet, I was at 1/6.

So very safely, I saved my game and got some sleep. Just to realize today that after loading my save, I'm now back at 0/6 AND an enemy home planet captured, which is purely impossible.

Anyone encountered this bug ? How to fix ? Do I have to play straight 6 hours the scenario in order to finish it ?


EDIT : after looking at my saves, I just found out there are different kind of "saves". There are manual and auto saves.

On my manual save, the objective was back to 0.
On auto saves, the objective is up to 1/6, as intended.
Why is it the case ?

REEDIT :

NEVER MIND, it shows 1/6 for 2 seconds, then it goes back to 0/6. What is happening :(

It seems like it takes a bit to check and update for objectives.

Speculative answer could be performance saving.
