Connect Memories achievement bugged

Hi!

Per the challenge description, a sequence may only be connected at the Memory Nexus once. The nexus does not count towards the 20-block sequence. Therefore, if you have a chain of 20 or more blocks placed that connect to your Nexus at two points, it will not mark the challenge as completed.

To put it in simplest terms, you need 20 placed blocks all connected together, those blocks need to be on 2 memory amplifiers, and need to be connected to 1 reward island anywhere along the chain, and they all must connect to the memory nexus on only one entrance. The nexus doesn't count towards 20, nor do distant memory reward islands.

Hope that clarifies!
