Hello, thanks for your answer :3
after testing all the powers, it seems i was wrong about "Concussion blast" as it worked today :s so i apologize about that >_<
BUT these powers crash the game with that same error message, as soon the casting animation ends (when effetcs should appear) even if no one's there :
Psionic Blast
Energy Wave
breath of black dragon
found out also that Summon Planar ally (the 3 elemental summons only), gives me an Objcreature.cpp at line 12162 error. can't seem to find the .cre files with Near Infinity, in the override folder.
Take "w_p710e.bam" (located in "w_psionics_unleashed\powers\energy_wave\copy"), rename it to "w_p301.bam" and paste into your override directory. Check if psionic blast still crashes the game.
Yup, still does.
