[Solved][1.1.60] Can't import longer blueprint strings

[asheiduk]

[...]I think what caused me to believe this was [...] the fact that I didn't realize it didn't natively exist in game before 0.15 [...], and then not too long ago I came across a thread with a "blueprint string" from 0.13 that made no mention of needing a mod to use and someone else posting saying the game was giving them a message about failing to import.

Just for reference: The mod Super Old Blueprint String can import these old strings.
