Powerups use a bespoke "CGenericPowerUpItemEntity", and don't work when used in the usual "CGenericItemEntity". That script function is probably trying to apply the powerup as a generic item, so it has similar problems. There's likely nothing you can do on that front.

Probably the best you can do is spawn the powerup item directly on top of the player, setting it to "Only first player picks".

Thank you!

Its working. I already tried to spawn exact item upon player, but i had wrong bespoke under which it was created. It was "CGenericItemEntity".

Also very confusing that in template there is four outdated types as

"CPowerUpItemProperties",
"CInvisibilityPowerUpItemProperties",
"CInvulnerabilityPowerUpItemProperties",
"CSpeedPowerUpItemProperties".

Which all point on now missing power ups in empty folder.

With the only correct one "CGenericPowerUpItemEntity".
