@zepumph - this appears to me to be a duplicate of #215, which apparently just crops up occasionally. Assigning to you to determine whether to just close this one and continue working on the original. If you do, please note in the original that the problem cropped up again.

Duplicate indeed! And on my list once phet-io priorities come back around to this sim.
