I get a crash when I try to write values into a constant combinator with the BAD chest command 31 but I give no signals to write.
I'm using Recursive Blueprints+ 1.4.17 and no other mods, but the sandbox scenario.
All this needs is a cheat electric energy interface (probably redundant), a substation, an empty BAD chest, and two constant combinators next to the chest. The constant combinator on the left is connected to the BAD chest with a red wire. It is set to send 1 on letter X (to target the other constant combinator), and 31 for BAD command. Normally the BAD chest would want to read the signals to write on the other color of circuit wire, green wire in this case, but nothing is connected by green wire in this case. When I enable that constant combinator, I get this crash:
50.472 Error MainLoop.cpp:1468: Exception at tick 3606: The mod Recursive Blueprints+ (1.4.17) caused a non-recoverable error.
Please report this error to the mod author.
