Tough 2000 Resin Acting Weird

Hey, I’m using the Tough 2000 resin, and some parts I’ve recently printed have come out weird. On some thinner parts, there tend to be cracks, bends, and outright failures, the parts detach from the supports WAY too easily, and the rafts fold like paper. I’m looking in PreForm, and I’m fairly certain it involves the new touchpoint shapes, which look far flimsier than before. Is anyone else having these troubles?
