We just updated to 5.6 and all of our MetaSound Sources that use MSP nodes inside have a couple of nodes appearing in red and as errors. The MSPs don’t actually have these inputs anymore, yet they’re still appearing on the MSS. I’ve even gone ahead and re-saved all the MSPs multiple times (added test input, then deleted). That has fixed a bunch of MetaSounds, but unfortunately not all. We have probably over a thousand MSS so it’s not really possible for us to go into every one of the manually. Seems like a bug. Is there any way to fix this? ![image.png.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/6/9/569d599a189d75e372ed5d2ca14fd978fbd8caf1.png) ---

Hello! I’m not sure if I’m missing an attachment but if the errors are the same as this post, you can pull this small change to fix it: [Upgrading to 5.6 Metasounds Error - #6 by Minus\_Kelvin](https://forums.unrealengine.com/t/upgrading%5C-to%5C-5%5C-6%5C-metasounds%5C-error/2651218/6)
