Facing a rather peculiar bug. I launched a single rocket to Duna with two ships on it, a comm satellite and a lander. Comm satellite was the top portion and separated by a stack separator. Working as intended. Beneath it was the lander which was to use the drive section to de-orbit and land. However when the lander gets ~11km or so away from the comm satellite, connection is lost. I have an extended Communotron 32, a Comms DTS-M1 targeted at the satellite (which targets it back with the same and also has extended Comm. 32) as well as a Reflectron DP-10. I suspect that it has something to do with the part of the lander that was attached to the separator is a monoprop tank and not a probe core, so it might be the root part which has lead to issues in the past. Is this the likely issue and is there a fix? Is there something else I should check or do to fix this? It kind of sucks wasting all that time and effort on the lander to lose it like this, and I don't really want to temporarily disable RT for this.
