Power-ups display errors, don't clear during/between runs

[Jacekpapapolski]

Upon collecting a pickup you receive an error. When the pickup runs out you receive an error.
The pickup UI never leaves the screen so as you collect more powerups during your run the bottom left of your screen continously fills up with (now empty) powerup icons

Lastly when you finally die and then start a new run all previous powerup icons will be displayed in the bottom left from the previous run

The errors are:
