I have a similar issue as we wind down into Autumn (Tamworth, Australia). I did an inspection the other day and found that two of the outer (foundationless) frames have parts that ‘bulge’ toward another frame, and in one place the bees have joined the comb on the two frames together. It looked like a few drone cells together in one corner reduced the bee space between that frame and the next, which was being laid down, and so the bees maintained the space and built the comb with a bulge in it. The bulge was then maintained in the next (and outside) frame, which is only about 15% built.
Given that the weather is turning colder (13-27C today; 55-80F), should I leave them to it now? Or, as suggested above, try and shave back the bulging comb? Should I get rid of the small bit of wonky comb on the last frame and have them start again after try to correct the frame causing the problem?
