it is when the mobs are dying, that the lag is happening for me, I don't have chrome browser on my computer *gasp* yes some of us don't use it. :)
used another browser and it works fine, even the issue with being able to pick up items.
Glad to hear it!
Thank you for all of this detailed information and feedback! We really appreciate it!! We'll be looking into ways to reduce this lag / stutter for the next update!
