I've tried the fix with the DLLs dated to Apr 03, 14:09. Mostly no issues, but I have noticed two things so far: 1. In comparison with the original Engineer, it seems the Thrust displays have gotten a little bit jerky. I guess it's more performant that way, it just doesn't look as... fluent, I guess. 2. Turbojets seem to produce wrong Thrust information which results in wrong TWRs which results in critical mission failure. At first this happend to me with a B9 part, but I just tested the stock Turbojet, see here, the discrepancy is almost factor 2. Oddly enough the Turbojets say max thrust 225kN in the tooltip and basic jet engines do not seem to be affected.
