marble titan erroneously prevents untap of creature

[GoogleCodeExporter]

What steps will reproduce the problem?
1. play marble titan 
(http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=84533):
"Creatures with power 3 or greater don't untap during their controllers' untap 
steps."
2. increase power (and toughness) of a creature with power less than 3 to 3 or 
more until end of turn
3. tap the creature

What is the expected output? What do you see instead?
When the creature's power is reduced to less than 3 at the end of turn the 
creature should untap during the next untap step.
Instead the creature remains tapped.
Even destroying the marble titan does not allow the creature to untap.

After destroying the marble titan other creature are not affected anymore but 
the tapped creature remains tapped.

What version of the product are you using? On what operating system?
Version 0.18.6 on Android 4.1.1

Please provide any additional information below.

A meekstone artifact 
(http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=11398) was 
also in play but I'm fairly confident this problem didn't arise until after the 
marble titan was played.

Thanks for confirming this, I wanted to prepare a similar test case but since 
this is only possible on Windows I was unable to.
