Save failed. I'm pissed off

I am playing StarCraft Mass recall
https :// www .sc2mapster.com/projects/starcraft-mass-recall

And hell, every time I win a scenario, when the next one is loaded, I’m completely unable to save the game! The file is created, but the game gives a “save failed” message instead of the usual “save succesful” and the file is useless as it cannot be loaded. I have to start the next scenario from the SCMR launcher to be able to save. I’m told that it is not a bug in the mod but in SC2 instead, so that’s why I’m posting it here.

PD
Just in case, just to be sure, I am playing this mod on Windows, since it doesn’t work on Linux. But but that’s Wine’s fault (the people at WineHQ require me to use plain Wine without Lutris or PlayOnLinux to report issues, and arcade and mods seem to never be tested by them, things like Chef of Aiur, StarBow, and such will crash at any time on Linux)
