nearinfinity compiler issue

i noticed that even if in state.ids 0x00400000 STATE_IMPROVEDINVISIBILITY is listed
when i use it... the compiler gives an error...
what is strange is: both STATE_IMPROVEDINVISIBILITY and 0x00400000 get red by nearinfinity as:
STATE_IMPROVEDINVISIBLITY

is there any workaround ? i tried to put a longer word but probably the parser has no problem in recognizing the string... also what is strange is that even 0x00400000 point to INVISIBLITY there is an I missing...

another error of the compiler was a missing entry in SPELL.IDS but somehow i fixed it putting a number instead of INNATE_SLOW_POISON
