ChaosCaching plugin appears to break packaged games. No warnings/errors reported in the log or when attempting to open the produced .exe. My task manager does not show the game process running at all, however a couple background processes do open and close upon double clicking the .exe (BootStrappedPackagedGame and UE4).
Result: .exe does not open, no crash reported, task manager does not show the game running
Expected: .exe opens as normal
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-106781 in the post.
