It was re-worked for v1.39 and has been through multiple tests here, and all functions, including the ST, which works in conjunction with the SJ. It is not nearly as "forgiving" as the Balao, if it comes early though, and is definitely more prone to issues, including in TMO, which is where the one in FotRSU came from. We desire to find the time to re-work ETR3(SS)'s Tench Class for inclusion with FotRSU someday, as well as a couple of other subs, and some AI units, but alas, "time" keeps on ticking ticking ticking...or was that "slipping"??...
into the future...
