cannot set properties of undefined

I've been experiencing lag and jerkiness lately and when I check the console, this is one of the errors I see.

Uncaught TypeError: Cannot set properties of undefined (setting '_leaflet_pos')

What are you doing when this occurs? Just panning?

Can you try two things for me:

1. Add verbose: true to the code block
2. Please show me your code block

Is this still occurring?

I honestly have no idea, I've been super slammed at work :( sorry!
