Stuck waiting for TX?

Hi, currently I have written some code based on the ss_twr github code, using the initiator interrupt and responder examples. Currently, I have code that switches between a responder and an initiator periodically. The ranging scheme works like normally for the most part, but randomly the initiator will get stuck waiting for a TX interrupt that never occurs, so it sits there waiting forever. I am not sure how to fix this. I saw something on the forum that talks about tx clocks, but I am unsure if that is referring to the same problem I am having, and how exactly to implement the solution. Any guidance is appreciated, I am at a loss.
