[1.1.1] Crash upgrading moded loader in blueprint: PrototypeError::~PrototypeError()

[gheift]

When creating a blueprint of a belt and a kr-loader (Krastorio 2) and try to upgrade the entities in the blueprint window, the game crashed.

Mods used: Krastorio 2

Steps to reproduce:

1. place a transport-belt
2. connect a kr-loader
3. create a blueprint of these two entities
4. click on "upgrade items"
5. click on "Default upgrade"

The order of building transport-belt and kr-loader is important. In the attached save, on the left site, the belt was placed before the kr-loader, on the right site the belt was placed after the kr-loader. The crash happens only with the left two entities.

Kind regards

Thanks for the report.
I was able to reproduce it in 1.1.1, but was not in 1.1.2, so it seems it has been already fixed by some other fix.
