IC Compilation Error - Multiple Registers Connected to an Input

[stachurr]

I read in a similar discussion post that in-world circuits may not compile in ICs due to a strict rule set. Based on that post & answer, I've explicitly excluded back-propagation and multiple sources driving a single output yet I'm still unable to compile.

Any help/information is greatly appreciated. Here is the blueprint I'm trying to compile (3-bit ripple-carry adder).
Thank you!

Hi. I labeled your image with the issues. You can see that there are multiple gates driving a single input of another gate. You have to explicitly OR together these signals. Let me know if you need more clarification.
