Description

Inform's parser allows multiple commands to be expressed on a single line, e.g. "GO NORTH. GO EAST." or "DROP PEPPER THEN GET KNIFE". Calling env.step with such an argument will cause an exception in Inform7Data._gather_infos.

Reproduce the failure by calling env.step with a single argument containing multiple Inform commands, then trace the exception in Inform7Data._gather_infos. The issue is done when both dotted and THEN-separated command sequences no longer crash the gym and are handled correctly.
