3 particular BPs cause level to crash

Development Programming & Scripting
1

So as of last night, i was working on a level and everything was fine. This morning i try to open level and it crashes every time. After a bit of investigation, i found that 3 BPs are causing editor to crash. Once i removed them i could open my level just fine. Kinda sucks as they were 3 main blueprints i was working on.

It was late so i cant fully remember but I think last thing i was working on was adding an interface so each of these could communicate.

Is there any way to remove rogue nodes and recover these?

Couldnt seem to upload anything here so had to use dropbox. File is only like 100k – Dropbox - BadBPs.rar - Simplify your life

Edit
As noted by I did get “No version info recieved” error when opening up launcher before finding issues with these BP’s. I didnt think they would have been related, but after reading some more, they just might be.

I have exact same issue. Everything was fine until last night when this happened to many users: Error! No Version Information Received - Getting Started & Setup - Epic Developer Community Forums

I have gotten my level to open up by using some migration workarounds, but if I try to save troubled blueprint I get following crash: Engine Crash on Saving Blueprint [v.4.5.1] - World Creation - Epic Developer Community Forums

I think this is a more universal problem more I read.

Ooh good catch! I did get that error when i opened launcher too. I just figured it had to do with not being able to connect web or something.
