So, this was resurrected while... Others were doing the work...
You could have checked on the status of the various 'forks' that had come about to take over the work on upgrading and fixing the various problems in the mod....
Like Shadoxa, whom had taken this from the old Version: 1.0.16 dated 2024-01-07 up to Version: 2.0.64 dated 2026-02-24 (which incorporated Main Game version 2.0+), until they had dropped supporting the mod in Feb 26. see https://mods.factorio.com/mod/Transport_Drones_Continued
And then, Hellwatcher, whom has taken this from the last of what Shadoxa had done, with Versions: 2.0.65 dated 2026-07-30 up until the recent Version: 2.0.158 dated 2026-10-21. see https://mods.factorio.com/mod/Transport_Drones_Continued_Fixed
in a way, this mod has now become the fork of the fork....
And Hellwatcher is working on 2.1 support as well... So, maybe you two should compare notes or something...
And you are all of the sudden back on this but no one really knows because they have moved on.... I'll expect that many things that you are currently fixing have already been address in one of the many updates by either of those two continuations of this, above...
And you know, they sited your work in the changelogs of their forks...
