Hi,

While copying and building the copy, I got this error:

The mod Quality Heat Pipes (1.1.2) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event quality-heat-pipes::on_robot_built_entity (ID 18)
Unknown entity name: legendary-legendary-heat-pipe
stack traceback:
[C]: in function 'create_entity'
quality-heat-pipes/control.lua:15: in function <quality-heat-pipes/control.lua:1>

Same issue here, also upgrading heatpipes with an upgradeplaner causes to crash.

Interesting interesting interesting, I need to sit down this weekend and fix some stuff

I was able to replicate this issue when creating and using blueprints. Should be fixed.

Works for me, thanks.
