I don't know if this was caught or not, but the choose signal semaphores from 1860 to 1918, the Early and Intermediate versions have the same intro/retire date of 1880 to 1918. I made the corrections and make the .pak files, however, these don't include the changes that were mentioned above as I did this last night. Here's the .dat main file for what it's worth with the corrections to the intro/retire dates. I noticed in the GitHub, the same error was present in the .dat file. Essentially, you don't have choose signals for twenty years between 1860 and 1880, but as I said, that's corrected here, just not the other signal issues. I guess I'll have to repak, haha!
