Thanks for the bug report @relifeted,

There seems to be an unexpectedly nil instance in the state. The relevant stack trace is:

panic: runtime error: invalid memory address or nil pointer dereference

@jbardin I think it's a dupe of another issue I have opened #21740 . Do you think this will be fixed in the 0.11.x series?
