My fourth land was not available to tap...

Same for me. Caves of Koilos couln't be tapped. I lost one turn on that match.

Mountain wouldn't tap for mana for two turns. Then on the following turn it suddenly could tap, but by then the game was too far gone. Third loss of my draft.

I'm a bit worried, as this big head years and it is still to be fixed.
White land doesn't tap, not manually, neither automatically

Same far left land unable to tap all game.

it's like one land is missing, but it's not

played a land, game crashed than it doesn't tap

I have had this issue twice, one with a dual land (next turn) and one with a simple plain. As you described both times the land was at the left and couldn't be tapped or used on any way even with autotap.

Both matches I lost too because of that haha.

I attach an image showing that land cannot be selected.

Same issue experienced today, lost my draft because of it

i experienced the same issue today

I experienced the same issue during day2 of arena open, lost the match and i have been eliminated as a result.
Is technical support investigating on this or they accept this bug as part of MtgArena? Seems a lot of players experienced same issue here...

I had a similar issue with a swamp in Historic. My turn was mostly skipped, I was able to play the swamp, but not tap it for mana, or have it auto included with casting an Ashiok.

I had a similar issue in a game today. Was unable to tap an island for mana

I played a plains in a neon draft and I couldn't tap it for mana.

I just ran into this playing a Plains in NEO draft. I can zoom in on the card, but Arena won't tap it, let me tap, or count it towards auto-tap solutions/auto-passing and it shows a blue outline under the land sometimes. My opponent didn't seem to be able to see it on the battlefield.

Update: And it definitely lost me the game.

I have lost two draft Games because of this

me too

My first land wasn't recognized either. Likely the same bug.

How do we get this bug noticed or fixed? It's been around over a year

I also had this problem. Land enchanted with Glittering Frost would not tap. I could look at the land enlarged, but it would not tap. This caused me to lose a draft game that I paid for, and I require a refund.
