Clear cache on nightly update

[lunar-seal]

Sometimes, I experience bugs on nightly that get resolved on pressing the clear cache button.

Those bugs can't be attributed to a particular version. Is this bug a remnant of the last version, or is it this version?

I propose to make nightlies automatically clear the cache on update.
If the build hash changes -> clear cache.
Does this sound like a good idea?

I thought about it and i guess it's a bad idea, first because we have no real clue when it was after an update, i guess the solution is to be sure that our cache is good
