A clear and concise description of what the bug is.

Attaching dynamic lights doesn't work for things and frames added through dehacked

Steps to reproduce the behaviour.

See examples in the attached wad.
Only things < 252 can have dynamic lights attached, and only on sprites < 245.
A modified vanilla object cannot have a light on a frame using a new sprite.
A new dsdhacked object cannot have a light on any frame ever.

When initially submitting the report, I thought this affected dehextra objects as well, but I was off by one in thing number.
So the root cause is probably the same as in #2619.
