Problems with 4.2.1 and 4.2 Beta

[QC102 0]

Trying some Sunlu Gold filament on "statues / Figures"  I  started with a Buddha followed by  "Oscar and Maltese Falcon files off Thingiverse.  Each when dropped into Cure 4.2.1 and 4.2 flashed the not watertight warning.   Used the mesh extensions and "repaired" them"  Each failed showing what  looks like the Fuzzy Skin had been applied... thought it remains unchecked.

After the first failure I also tried the "repair" using Ideamaker - which  signaled the file was now OK. All teh files are scanned figures  rather than "blocky" stuff conjured up in Tinkercad and all other  models printed in either of the Cura version had problems.  The picture of the Maltese Falcon, sliced in 3.6. small version was the test piece and both look  OK. It seems that the Mesh repair tools in 4.2.1 and 4.2 are in some way affecting  the structure. I submit this to check if others have these same issues. with teh version above.As it is I just use 3.6 for other figure models.
