Forge Release 11/10/2018 ver 1.6.18

[Fregnor]

Vicious Rumors does not get all of its effects. The opponent does not discard a card from the hand to the graveyard.

[CokedUpZombie]

Maze of Ith seems to not work correctly. Is there a specific phase it must be used in? Cannot block Mutavault at all or creatures with vigilance.

[peepser]

Old man of the sea gains control of desert nomad, causes crash.

[eggelton]

Kiora, the Crashing Wave's first ability doesn't seem to work correctly. AI creatures targeted by Kiora's ability are still able to deal damage to planeswalkers.

Maze of Ith seems to not work correctly. Is there a specific phase it must be used in? Cannot block Mutavault at all or creatures with vigilance.

Just tested Maze of Ith on my own vigilance creatures and on Mutavault. This seems to work fine. You can only target a creature after it has been declared an attacker. If you try to Maze of Ith something during the declare blockers step, you first must declare blockers and then target something with Maze. I think it might just be a timing thing, because I can verify it works.

Maze of Ith

So I think my issue is that it doesn't work during declare blockers step. I guess if I miss activating during declare attackers then I cannot stop them. See attached.

[lindleya1]

Xantcha, Sleeper Agent is bugged. In multiplayer, even when affected by "must attack this turn if able" Xantcha won't attack at all.

[lindleya1]

Also, the AI won't remove counters from Arixmethes, Slumbering Isle

[peepser]

When Orzhov Advokist is out, AI never uses it to add any counters to its creatures. Also, it lets me add counters to my creature on my turn, and still attack the same turn I added them. This is extremely overpowered.

[darksepho]

Epochrasite doesn't work, it get exiled when it dies but it doesn't get time counters.

[Mrs Non-Gorilla]

Fast-flickering Reality Acid (as with Felidar Guardian) still leads to a broken sacrifice trigger. (The trigger goes on the stack, but doesn't do anything.) As reported here for 1.6.17.

[Mrs Non-Gorilla]

If I use a Clever Impersonator to copy a planeswalker which has already used its loyalty ability for the turn, the copy is treated as though it too has used its loyalty ability for the turn. I've had this happen with Mirror Gallery in play, so it's definitely not just that I'm keeping the wrong one around.

[MrMystery314]

The game freezes when an Albino Troll equipped with Fleetfeather Sandals that has been targeted with Serendib Sorcerer's ability is blocked by a Vesuvan Doppelganger copying Apothecary Geist equipped with Hot Soup when the Hot Soup trigger goes on the stack. And yes, I realize that is a bit weirdly specific.

[eggelton]

Knowledge Pool doesn't work correctly. With it in play, when its main ability triggers, the player is prompted to select an exiled card to cast, but upon selecting that card, it isn't cast and Forge re-prompts the player to select a card, with the list no longer containing the selected card. It re-prompts like this over and over until the list is empty, without any selected card having been cast. This happens intermittently, not consistently, so sometimes Knowledge Pool works correctly, sometimes it just buggers out.

[ProphetSword]

Maze of Ith

So I think my issue is that it doesn't work during declare blockers step. I guess if I miss activating during declare attackers then I cannot stop them. See attached.

I'm curious if you have screenshot of the other cards on the battlefield. I had a similar issue once, and I'd like to know if your issue turns out to be the same as mine.
