However, re-connection would be -required, to avoid stalling all banks/cards in the event of a connection -loss to the server. +We use the [issue tracker of the osmo-remsim project on osmocom.org](https://osmocom.org/projects/osmo-remsim/issues) for +tracking the state of bug reports and feature requests.
