Oh, actually it's clicking. After one click the skills aren't assigned anymore.
Oh ok, that's intentional.̆ This allows you to regain control from the replay, kinda like how Cheapo handles replay.
Indeed, you can use the record/replay feature as a sort of rudimentary save state.
Which reminds me: I don't remember if Eric documented this or not, but right now during playtest mode, you can press F to toggle fast-forward on and off, even during replay.
BTW when I try to play the Havoc 10 recording it says "no compatible graphics set found". I changed the config file to point to the right set, but it still doesn't work.
If you made changes to the LemmixStyle.ini while Lemmix is still running, you'll need to quit and restart Lemmix so it picks up the changes to the config file.
Also, to clarify, are you only having problems replaying the solution, or are you unable to even open the Havoc 10 level in dlvel000.dat of ONML?
Then again, Eric did update something related to ONML game mechanics between 0.0.7.0 and 0.0.8.0, so maybe it's better for me to re-record the Havoc 10 solution (the change shouldn't affect the solution at all, but what the heck).
