when you have a stargate in the overworld hooked up to open computers it will not dial to any other dimensions (DHD and PDD will dial succesfull), it will only dial to stargates in the same dimension. The stupid thing is dialing with a computer from an other dimension like the nether it will dial with no problem.

so i dialed with the lua terminal to see if i get an error but it gives non. The gate will even begin to dial and then after a second or so it will just stop, no error, no explosion....

What build are you using?

2.0.4 - bugfix - 1

2.0.5 has also has the same issue

I need a video or something showing the issue. I cannot reproduce this.

i will make a vid tomorrow.

also after some more testing i found out that if the chunk where the gate is in in the other dimension is being loaded (for example by a chunk loader from IC2) the other gates has no problem dialing to it.

here is the vid:

as you can see, when the chunk in the other dimension is being loaded it has no problem dialing to it. so my hypothesis is:
when you dial interdimensional the chunk in the recieving gate gets loaded, so the outgoing gate starts dialing out with no problem. But then aftar a tick or so minecraft unloads that chunk again and with it the recieving stargate, so for the game the recieving stargate doesnt exist anymore and the outgoing stargate powers down.
