The simplification property test crashes (again).

Today I've had a test fail that was unrelated to my work. It can be reproduced with:

stack test --test-arguments "--hedgehog-replay \"Size 79 Seed 11061009888786495411 89260594792354819\""

Output:

` ✗ simplify returns simplified pattern failed at test/Test/SMT.hs:31:24 after 1 test.

              This failure can be reproduced by running:
              > recheck (Size 79) (Seed 11061009888786495411 89260594792354819) simplify returns simplified pattern

          Use '--hedgehog-replay "Size 79 Seed 11061009888786495411 89260594792354819"' to reproduce.

It seems the same test has failed in the past: https://github.com/kframework/kore/issues/1342.

Later Edit: Also here https://github.com/kframework/kore/issues/1467.
