Hello,

I’ve noticed 2 issues in the recent update of coot (v0.9.8.5 from CCP4i) on an 
Intel mac updated to Ventura (13.0.1). I did not test on Linux.

When I delete a molecule, my Coot/X11 window « disappears ». It is not 
closed/killed but somehow minimized. I can get it back from my dock, but a bit 
annoying.

Here’s what the console says.

(set-delete-residue-mode)

O" at (26.959,-34.446,11.593) : 0.132

debug:: g.safe_scheme_command() with command post-manipulation-hook

When I build sugar chains with the N-linked Glycan module, they are not 
building correctly. It looks like it messes up with the wrong atom for linking.

When I try to add an Aplpha1-6 FUC residue to my initial NAG, here is what the 
console reports

In this case the FUC residue is quite far from the NAG residue upon refinement

Hope it could help
