Hi there!
Phobos is unreachable for us - we've tried reaching it on a Tier 2, 3 and 4 rocket, but neither works.
Renaming the Dimension ID made the button turn green but it remains non-interactive.
The dimension clearly exists, the blocks show up in NEI, yet the moon itself cannot be reached.

Change the ID of Phobos on the server and on the client!

Thank you so much! That did work, however, on arrival on Phobos I spawned on block 900something, without the Landing ballons (or my rocket for that matter). It was easy enough to replace, just wanted to let you know this occured.
