Anti Tank Mines Disappear After A Few Seconds

I have the same issue, is there a way to fix it or we must wait the developers to resolve that?

I know this is an old thread but this has been happening to me since last update.

Product: Battlefield 2042
Platform:Steam-PC
Please specify your platform model. PC
AMD or Nvidia Model Number RTX3060
Enter RAM memory size in GB 32
Are you using any software with an overlay? No
Which part of the game is the issue happening in? Multiplayer
Which part of the mode? Breakthrough
Please select your region North America
On which server did this happen? Official Servers (All)
When did this happen? (dd.mm.yy hh:mm) Often. Last tested 28th Feb, 2024
Summarize your bug During the countdown between changing sectors in Breakthrough (a sector is captured by enemy and friendly forces must retreat to next sector), anti-tank mines will disappear EVEN if they are placed in the new sector once the countdown between sectors is completed.
How often does the bug occur? Often (50% - 99%)
Steps: How can we find the bug ourselves? As Defender in Breakthrough, while playing as an Engineer, when a sector is lost and the countdown starts between changing sectors, place anti-tank mines in the new sector.
What happens when the bug occurs? Once the countdown is complete, all anti-tank mines will disappear even if it is in the new sector.
What should be happening instead? Anti tank mines should remain placed in the new sector when the countdown is completed. It is up to the game designers to decide if the anti-tank mines remain in the previous sector (which is now blocked off for defending team).

During the countdown between changing sectors in Breakthrough (a sector is captured by enemy and friendly forces must retreat to next sector), anti-tank mines will disappear EVEN if they are placed in the new sector once the countdown between sectors is completed.

Anti tank mines should remain placed in the new sector when the countdown is completed.
It is up to the game designers to decide if the anti-tank mines remain in the previous sector (which is now blocked off for defending team). As Defender, I would like them to remain but as an Attacker, this would be annoying.

Additional Note: This is not the same as trying to lay more than 3 mines as an Engineer (which would replace the first mine that was placed with the newly placed mine -- the 4th one)

@Dana8610I have narrowed down the (or a?) cause a bit instead of a general 'it disappears' to it being between changes in sectors. Here's the thread I posted the details on. See if it matches your experience.

I've merged a similar thread with this one.

I've noticed that too, but it doesn't happen all the time. Even if I wait when the sector is open for enemies, they sometimes disappear too. I can be standing right next to them, there's no one around to take them, and they don't explode. Just...poof. :D

So, I played again last night. I was on Manifest, last objective. I purposely waited about 30 seconds after the sector opened to enemies, stood by the mines. They disappeared one by one in the order I placed them down.

When I used the mines in the rest of the match, some disappeared and some stayed. I'd really love to know the cause, since it's so random.

So I thought the new season would fix this, but it's still happening. It's really annoying, I waste them and need to hunt for an ammo crate, which usually isn't anywhere lol.

Resurrecting this thread to mention that it still keeps happening. 100% of the time in Breakthrough when the defenders get pushed back to a new sector. The mines don't explode, they just disappear. I have to wait for the second siren to sound to lay them down and not disappear, which is pretty inconvenient.

Also I'd like to add that it's not just anti-tank mines. Basically any deployables - claymore disappears, Irish's sentinel and cover break down without anything shooting them.
