Ok, so the issue happened because you named the individual constructions that make up the dynamic construction 0 and 1. I implemented a fix that will catch this case and still allow the simulation to proceed:
However, I hope I’m not being to critical by saying that 0 and 1 are really not good choices for construction names that are supposed to be unique. Even something like Tint_0 and Tint_1 would be a huge improvement. Or you could just leave the _name_ blank and use the auto-generated one. As a general rule throughout the LBT plugin, if you aren’t willing to come up with a genuinely unique input for _name_, then you really should just leave it blank and take the default. You just open yourself to a lot of weird errors when you use _name_ inputs that might not be unique.
