Instability arrgh!

I griped about this before as a general complaint, but didn't provide an example. Here is an example.

I build a model, all is fine. I do ANYTHING that causes a recalculation, and F360 suddenly finds warnings and errors.

I go back in the timeline and look at a bunch of yellows and reds. Go to the first one, a Split Body (split solid by a curvy surface previously developed). Double-click in the timeline to open that operation... do NOTHING except hit OK. It calculates for a moment, then says "OK fine LOL, joke!". And all is OK again.

Go through and fix a number more of these issues, all same... "...LOL, joke!"

Hit "Compute All", and all the same errors reappear. 

Attached screen cap vid: I open the first red op in timeline, hit OK, it computes ok, the red goes away, and I'm told about the remaining issues.

Thanks for sharing the problem! Can you help to share the dataset for confirming the problem and do some further investigation?

Thanks,
Steven

Here it is, thanks!

Thanks so much for sharing the file! Yes, I can see the behavior too.  I have logged an internal defect(FUS-117154) to ask development team to take a look. 

Thanks,

Thanks!

For another degree of instability: Without me changing anything, that first op suddenly stopped allowing the click-through fix... it remained broken. I redefined some geometry and was able to delete the Split Body op, and now all is OK.
But this remains one of my biggest gripes: F360 refusing to split a body by a somewhat complex surface (can't do it, result invalid, compute failed)... even when I can look at the bodies and envision the obvious result, it SHOULD work!

Another instability example: Doing an operation such as a sweep, and a good body is previewed, but when I hit OK F360 throws an error (invalid body or something to that effect).

The last big gripe is inability to offset or thicken a surface, often surfaces which are a loft to a point, which I use ALL the time. Maddening.
