[fixed]Dark Depths doesn't interact properly with Urborg

[umborg]

Describe the Bug:
When both Urborg, Tomb of Yawgmoth and Dark Depths are in play, but it isn't possible to produce enough mana to activate Dark Depths' activated ability, Dark Depths cannot produce black mana.

As it can be seen in the screenshot below, it's not possible to tap Dark Depths, even though it is untapped and Urborg is in play:

Interestingly, Vampire Hexmage still shows as being available to cast.

When another land is in play, in this case Sejiri Steppe, and Dark Depths' activated ability cost can be paid (3), you can then also tap it for mana:

It seems like Manalink only considers the mana ability a possible action for the player if the activated ability is also possible. After tapping it for mana it automatically/ immediately prompts you to also pay for the activated ability cost, which you can then cancel:

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
I am using Manalink-3_0-July-2021_v1_1. The bug happens in a duel.
I am sorry to only have screenshots but for some reason I am unable to create any saved files and I couldn't find the autosave as well.

What exactly should be the correct behavior/interaction?
If Dark Depths is in play at the same time as Umborg, Tomb of Yawgmoth, I should be able to tap it for mana independently from Dark Depths' activated ability.

Are any other cards possibly affected by this bug?
My deck also includes the card Riftstone Portal, and the same bug happens as well, even if it is in the graveyard at the same time that Urborg is in play, as long as there are insufficient mana sources available to activate Dark Depths.

Thanks.

It's a couple of issues specific to Dark Depths, thank goodness. Working on them and checking the other lands with no mana abilities.
EDIT: fixed in b0f3cec

Thanks!

Sorry if this is a stupid question, but is it possible to play the build with the fix?

Not a stupid question. The change will be in the next patch.
