I'm unsure how this is a duplicate of an issue that was posted as of a year ago and affected a version of this game 2 updates back. It may be the same issue but it has resurfaced due to something in the latest update for me. This was not happening to me in 1.5 but it is currently happening to me in 1.6.1. Is this now how the spiders are going to behave from here on out?
You are correct the clients were set to normal but the server as was set to 1. I thought this was setting was normal as well but have researched and found that not to be the case. I have corrected it in the settings and I appreciate your explaining it further to me so I could get it fixed.
