This is an interesting one that you have decided to use.
SubFlags_0_0_8_byTheDarkWraith_2_Flags_IRAI_0_0_39
Adapted to work with IRAI which you do not have.
IRAI 39 also needed a patch that fixes a starshells bug that you may well have as you are using 'Stock IRAI.'
IRAI 41 is already patched.
Check this Post out #318
This might be better.
