I have a pb. Not sure it is specific to 2.8, but perhaps.
I create a basic “cup”, Rigid Body / Passive
I have an UV sphere, above. Rigid Body / Active , MAss 0.03 Damping Translation 0.35 / Rotation : 0.6
I put a Wind into the cup, strength 20
Then i animate it seems to work, the sphere reacts slowly to Wind and suddenly, near frame 220, it is violently thrown away from the cup, with a very high speed.
I tried different new projects, with similar contexts, and i always have this problem : suddenly, things are very violent.
Any idea of the pb ??
