Crash when auto connecting pins in 4.26 #26

Closed dev2-just2devs closed 3 years ago

dev2-just2devs commented 3 years ago

Hi I keep getting crashes in 4.26 every now and then. I haven't been able to replicate it consistently but it seems to be happening when auto connecting variables to function pins.

Here is the crash logs:

I just submit a fix to marketplace,it should solve the auto connect a typeless pin crash issue.

It doesn't happen with a typeless pin for me, it happens with any pin.

The update is not released yet,its being reviewed by marketplace at this moment,maybe wait for several days. it should solve a common issue with auto-connecting.
