Wood holds probably even more chemistry than paper. You might wanna try the Rollei/Maco emulsion hardener it's put into the developer instead of the fixingbath. Use the stopbath for twice the recommended time for normal paper (might attack the emulsion so pre-hardening is recommended)
Again good luck.
hardener is provided with the Foma emulsion - I never use it... (it's a total no-go if using the papers for bromoil prints..)

I think the issue could be in the thichness of the papers - the students (and me) are using the same emulsion - same developer - same stop and fix... and it always happens after the stop/rinse, so the difference between us has to be how we coat our papers - some thinner than others.... And if thick, then the stop might be insufficient..
