Unable to access mine shaft

I recently returned to Path of Exile after a few years, and started playing with my main character in Standard. When I tried to do Delve, I first noticed that my progress had been replaced with a straigt mine shaft to the approximate depth I had previously delved (no big loss).

However, I was (and still am) unable to teleport to any of the nodes in the mine shaft from anywhere, which in and of itself would have been a major annoyance. When I click a node in the shaft, the mine map simply closes and nothing else happens.

Instead, I entered the mine from the new starting point, and I can teleport to and from these positions as normal. Unfortunalty, I cannot get the cart to travel to any of the nodes in the shaft. The paths are marked as traveresed on the map, but they are not lit up in the game, and the nodes are not "discovered" when I manually go there. This is a real problem, as I was only able to explore a handful of nodes in the new mine before all paths crossed the shaft, locking me out of any further progress.

While getting this bug fixed would be optimal, I would settle (for now) with some sort of workaround; completely resetting my mine in standard would be acceptable.

Thank you, issue solved! =)
