Hello! Just did a quick check, it looks like RBJJ is working to me. There’s a separate action icon for using them as oppose to a normal boost:
As for Ace 2, iirc I temporarily skipped setting up the interaction between it and the jumpjets because it raises some thorny user-interaction questions about when to roll for the heat & ask for the movement target, but it’s on the to-do list to figure out.
Let me know if you have any more questions! Olive
