Hello, on our CI server sometimes we got following exception:

timestamp: 2019-05-22T09:05:16.435110
Exception caught: (pants.invalidation.cache_manager.IllegalResultsDir) (backtrace omitted)
Exception message:
The results_dirs state should not be manually cleaned or recreated by tasks.

The current_results_dir directory was not found
       * /home/bamboo/git/r9/.pants.d/compile/zinc/a53b6931478d/nucleus.java.com.r9.nucleus.commons.memoization.memoization/1cd408ba5a91

pants_version: 1.14.0rc3

actualy

/nucleus.java.com.r9.nucleus.commons.memoization.memoization/current

points to

1cd408ba5a91

and this does not exits. I did not find anything on our system what could delete that directory. Maybe some known behaviour?
