Strange and random (!?) error of the Control block

Hi everyone, sometimes it happens that I get the following errors, the problem is that they seem to appear in a random way, for example my design was working correctly but I needed to rename it...

This is a bug. Are you absolutely sure that this only occurred after changing the Control block path? I would be surprised if that caused it.

It's most likely occurring where an Adder feeds a Mux. Look at the blocks around Subsystem1/Subsystem/Mux in your design. Have you hard-coded the types on any blocks in this area? Perhaps you can pare down the design so that it only contains a few blocks and yet has this problem. If you can, please post it here.
