Hi Justin,

we re-added PyOP2 type-checking, which validates that you're iterating
over compatible sets.  Plausibly you weren't doing that.

You can set:

parameters["pyop2_options"]["type_check"] = False

in the short term.

Can you please report this as a github issue so it doesn't get lost
over Christmas!

Thanks,

Lawrence
