Hello

I couldn't find any post on that so I'm posting it.

I tried watching a replay earlier, but it didn't work because apparently "it was created in version 0.14.18, but current version is 0.14.19" even tho I just played on it, and saved it. Yes, I double checked.
Is it an actual bug or is it just that it is when the save is created and not saved ?

Thanks in advance.

With what version of the game did you create the map of the save-file you try to replay?

Replays cannot be migrated between versions (even minor releases). Every bug fix or minor tweak potentially changes how the game simulation behaves, which basically invalidates input actions recorded on previous versions.
