Buoyancy stopped working

Hello,

we are running into a stange issue where Water Buoyancy stopped working. I bade a simple Blueprint boat on Friday and it worked as expected. Followed the waves closly and looked great. However today on monday I opend up the project and Buoyancy is entirly broken without even makeing a change. (Did also a roll back on our version control).

Whats happening:

  1. r.Water.DebugBuoyancy 1 does show the water simulations is rater flat and not following the visual waves

  2. The Boath with it’s r.Water.DebugBuoyancy 1 is following a 3rd and entirly different wave pattern which does neither match the visuals waves nor the debug data

  3. Using the BP_BuoyancyExample, it will show the exact same issue with the change that the simulation stops after around 5 seconds.

Any idea whats going on?
