Do not trust Unity Collab.

Been using unity collab as a VCS for months on a project, regularly saving the files, working well.
Today i decided to refactor some code but lost track of some things, so i reverted to a version i checked in 2h before.

Unity replaced my files with the stable build back then, except... half of the files were missing. of course no undo functionality.
months of work were simply not saved in collab. no version had these files, i did modify them regularly and they never caused collab issues.

how can a company not make the vcs they add for their main product work to its minimal requirements?!

Im not sure how i could motivate myself to fix this mess. fuck this trash company, cant have a single project without major issues.
