Mutable compile hangs indefinitely when using Customizable Object Extension Data Constants - Redux

I’m still seeing this infinite compile issue in UE 5.7.1. As described in the community forum thread you can work around this by setting the Customizable Object’s compile Optimization setting to Minimal instead of Maximum.

The JIRA/issue link referenced in the previous UDN doesn’t seem to resolve to anything, or maybe isn’t public.

Any updates on this issue?

I am getting a CO compile to hang indefinitely while compiling. It seems to be caused by the optimization in LocalLogicOptimiserAST that tries to convert 3+ conditionals into a switch statement. It happens if you have 3 or more COs for an Object Group that are using a Customizable Object Extension Data Constant (for example, a Groom Constant). If I shut off this specific optimization, the issue goes away.

Hey there,

Apologies for the delay, we’ve just arrived back from holiday break. Yes this is still an issue and we are currently working on it.

The only work around we have at the moment is just as you mentioned, setting the optimization setting to minimal.
