lol no, its done intentionally.that's not how versioning works regardless, after 0.99 normally it's 0.100
If the goal was to keep updates numbered it would simply say update 99 , patch 100.
People are far more likely to check games that seem to be far in development. That is why the numbers get manipulated like this. Lets compare numbering of couple of first vs latest patches
0.1
