Possible issue, unsure. Save game version appears to change with every new commit.
During some testing, I receive the below in as part of the stdout output:
Incompatible savegame. Expected version 1.7.340.0.63a4a5f6, found 1.7.340.0.a86fa6a8
This could be be design, but wasn't sure whether it was meant to be picking up the git hash in this version or not.
