KSP 1.12 - Parts are bending/distorting on loading into world

[OrbitsR4Sissies]

I am seeing a LOT of this with 1.12 craft which have worked just fine prior to  1.10.

I do tend to use autostrut (heaviest or grandparent) but consistently. The parts that appear to be sagging are batteries (the larger 1000ecs), the Oscar tanks (placed in a line, horizontal to ground, parallel to craft body) and the Science Jr, when used as part of a body of an aircraft or rover. Not even Rigid Attachment helps here.

The behavior occurs BEFORE the craft is ever used, as it loads onto the runway, horizontally. I have not seen this occur on vertical craft (rockets).

The issue almost seems as if the craft has struck the surface, bending upward, even if the part can never bend.

Attempts to reinforce these by clipping fixed length items through them, such as a girder, has limited success. I don't tend to clip parts.

But even when I do not use autostrut, the behavior continues. When adding individual strut parts to reinforce these items, they sometimes stay in place.

Mods are mostly graphic now, only one non-stock part mod used (Bon Voyage). Others include Scatterer, AVP, EVE, Waypoint Manager and Waterfall.

I had just added the visual mods today, long long before these issues began.

I'm also seeing craft in space, while docked, become increasingly bendy on acceleration, forcing the use of manual struts to ward that off. I tend to use autostrut on them but never Rigid, which glues the ports permanently on loading.

Any advice or confirmation of issues with bending craft?
