Collectible Card Game Headquarters

Describe the Bug:
1- Holdout Settlement can't be activated for colourless mana.
2- Holdout Settlement 2nd ability can be activated even if you don't control a creature.
3- If 2nd ability is activated and then you cancel it you still get mana. When you select Holdout Settlement you are first prompt for what kind of mana to produce and produces the mana then land is tapped and then you are prompt for a creature to tap.

Which card did behave improperly ?
Holdout Settlement

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2016/08/27: Eldritch Moon v2, duel

What exactly should be the correct behavior/interaction ?
1- Holdout Settlement can be activated for colourless mana.
2- Holdout Settlement 2nd ability can't be activated when you don't control a creature.
3- If 2nd ability is activated and then you cancel it you don't get mana.
I don't know for sure/always confuse these: But seems logical to follow what is printed in rules text for order of things when activate it: tap Holdout Settlement then tap creature then select/produce mana.
Are any other cards possibly affected by this bug ?
-

Also 2nd ability to tap creature to produce any kind of mana doesn't give you opportunity to activate it in advance to counter spell.

Sliver Hive has also the problem that can't produce colourless mana.

Sliver Hive is internally completely unrelated to Holdout Settlement, and should probably only be able to produce colorless.

For the original bug, Springleaf Drum is a good template to crib from. (But see this bug first.)

Fixed Holdout Settlement issues in commit a85fc737.
Fixed Sliver Hive issues in commit 9f9383be.
