I paid for a B2-8 node (2 cores) hoping that it would allow me to run 3 backtests from 3 different projects at the same time: one per core for the B2-8 backtest node, and one from the community B-micro node with 1 core.

It seems that after upgrading my backtests no longer run on the community node. Did I lose access to it?

What can I do to use 2 cores from the dedicated B2-8 to run 2 parallel backtests?
