I would also check to make sure that the tissue wasn't held in an
something with a lot of alcohol, like RNA later.  I found out first
hand that it doesn't work well.  Good luck

Really weird part is that I have 20 blocks in this group and some are soft and others are just fine. Tried changing angle, new blade nothing helps. When I finally manage to get a decent section and pick it up on the slide, the OCT around the tissue want even pick up smooth it wrinkles really bad.
