some other possibly useful information here, it just seems to be
language 0 that is broken.

$ luatex '\hyphenation{foot-ball}\showhyphens{football}\end'
This is LuaTeX, Version beta-0.89.1 (TeX Live 2016/dev)
 restricted system commands enabled.

Underfull \hbox (badness 10000) detected at line 0
[] \tenrm football


no hyphenation but

$ luatex '\language1\hyphenation{foot-ball}\showhyphens{football}\end'
This is LuaTeX, Version beta-0.89.1 (TeX Live 2016/dev)
 restricted system commands enabled.

Underfull \hbox (badness 10000) detected at line 0
[] \tenrm foot-ball


any other language and hyphenation works as expected.
