The licensee was only able to provide the following information:
"The error was fixed by simply deleting everything from the node where this crash was happening, compiling and saving it as blank, and then ctrl+z'ing all nodes back. It probably is a serialization issue that happened somewhere along the line as we were working on it, so it's really hard to provide additional information. "
This crash has similarities to an older one fixed in 4.8 - [Link Removed]
