Mudrunner and Spintires conflicts

I reinstalled Spintires today as I had uninstalled it some time ago because of file conflicts.
I found that both Mudrunner and Spintires Editors share the same folder or cache.
This should not happen or be allowed.

Known issue, but I agree. It WAS resolved a while ago, but then an update reverted the cache location again and it hasn't been addressed by either Oovee (ST) or Saber (MR) since. More than a little bit of an inconvenience for those of us who moderate for both games...
