Turntables are tricky things to get set up optimally.
Warped records are always a problem, but more so with some setups than others.
Others might correct me, but if you hear the thump noise frequently regularly even with just modestly warping in the records, I'd suspect initially its most likely some combination of the tonearm having trouble tracking the record through the warp combined with a table system resonance occurring in the frequency range where the thump noise occurs.
All tables have resonant frequencies, but they can be tweaked in various ways using different combinations of tonearms of various mass and associated carts. There is info in agon forums and other sources on how to address these things.
Also, in general, higher mass tonearm/cart combos tend to have more difficulty in general trqacking through warped records due to the higher mass and associated inertia.
Its hard to recommend a specific solution to this problem, but at least these are the things I would say are worth researching and giving some consideration to to help remedy the problem.
