Updated legacy HUD not behaving for setting partner

[KittyCats Resident]

Meanwhile a third person reported the same.

She did however discover that in her case it helped to take her cats to a different place, where partnering them was no problem.

I was also able to test with my own cats at her place, but once again failed to recreate the issue. They detected the partner as both regular cats and in 2D mode.

Our next step will be to try to get together with one of the breeders who experience this, and do some testing with them.
