Hi, On windows 11 using chimera 1.12 I I had to modify an RNA structure by adding a 5’ G. Then I used Isolde to relax the region. However, after creating the new bond I was not able to see the atoms for the 2nd G. And after the simulation I was not able to display the atoms for almost all residues except for a select few!
