You can't deactivate mines of other players in multiplayer, using Wire Cutters doesn't work, it only works if the mine is the OWNER player.

Which SecurityCraft version and which Minecraft version are you using?

Hello, I'm currently using Minecraft 1.12.2 and SecurityCraft v1.8.23.1 (Latest update for 1.12.2)

Oh wait, I've checked it and the latest update is v1.8.23.2 and mine is v1.8.23.1, this version has that fixed?

No, that version only fixes a crash with the trophy system. I can't reproduce your issue, I can defuse mines owned by someone else just fine.

This is what happens to me... It has to be enabled in the config?

You need to rightclick the mine, not sneak-rightclick.

It also doesn't work

If you want, you can try it in my server, but I have more mods installed. Do you want?

No, thanks.

Can you enable the admin tool through the mod's config file, then rightclick the mine with it and show me the messages that get sent into chat?

This is other player mine, and I want to deactivate it but...

Not sure why you tried to rightclick the mine with the owner changer... I only did that in my video to make the mine owned by a different player.

I see, it works with a normal mine, but with a Block mine doesn't, can you try it? Also you can't remove the mine block of other player

Block mines like the dirt mine or stone mine cannot be defused. Removing mine blocks is only possible if the respective config option is set properly.

Here you can see it

And what is that configure option?

options {
B:"Are mines unbreakable?"=false

Like I said, block mines cannot be defused. It's not possible.
And yes, that is the correct config option. However unlike what it says, you need to set it to "true" instead of "false". It does the exact opposite of what it says it does. That will be fixed in the next version of the mod.

It explodes when I break it if I enable that option to true, is that how is supposed to work?

Yes, you need to defuse it first to break it safely.

We'll talk about that internally.

Since this issue seems to have now been resolved, I am closing this.

Thanks. But also you need to add an option to defuse block mines, because having a furnace mine inside of your house without any way to defuse it...
