Hi, there is a project which validates slices and configurations submitted to issue tracker. Lately Iâve discovered a couple of issues and opened cases about them: https://pharo.fogbugz.com/f/cases/18502/ https://pharo.fogbugz.com/f/cases/18499/ Also one of my tests is regularly failing during validation. The test checks if certain singleton is updating itâs cache when a class is removed. For some reason during validation the object is not subscribed to the system announcer any more. I need to know if there is something special happening in the CI worker, I if I need to manage the subscription in a different way. It would be really nice if someone who is familiar with the CI project gave me a hand because it takes plenty of time to understand how it is working⦠Cheers. Uko
