This was fixed in the past few days. If you're running a Windows server, I'm not sure if the build on the site is updated.
You want infinitely chainable rolls, long/JK2 rolls, and to roll whilst gripping someone? Try adding 4 to the value.
japp_fixRoll uses a bit-value, so for 3 options you can use values up to 7 to combine then. 1 + 2 + 4 to enable all options.
Unfortunately this hasn't been added yet, but it's on my TODO list.
I should be able to do it in the next week or so D=
Ah, didn't realise that was still a condition.
Fixed =]
