the objective of my manager is apparently to make this one work, so it doesn't cost too much to rebuild everything.

Yes, that's the old "fix it but don't change it" manager mind-set. :rolleyes:

Ceramic 0.1uF decoupling capacitors definitely need to go to a ground point nearest the op amps with as short leads as possible.
Otherwise they are not effectively decoupling the amps and they are still likely to oscillate.
