Thank you for reporting this. We currently have a bug report in for this issue back from 4.8 which was never technically fixed. The issue kind of disappeared with 4.9 so we assumed that it was gone and there was no way to test if a fix would work when you can’t get the issue to happen. I’ve bumped the report to let people know that it’s occurring again so that it has some attention now. Otherwise, please direct any more information questions to the old thread we had, which also got bumped recently: Erroneous SVN checkout spam on blueprint compile - Programming & Scripting - Epic Developer Community Forums
