I just tested, still there is the same error, I am in Unity 6 now.
Net.FabreJean.PlayMaker.Ecosystem.EcosystemBrowser+<ProceedWithImport>d__107.MoveNext () (at Assets/net.fabrejean/Editor/PlayMaker/Ecosystem/EcosystemBrowser.cs:2904)
Net.FabreJean.UnityEditor.EditorCoroutine.update () (at Assets/net.fabrejean/Editor/Plugins/EditorCoroutine.cs:53)
UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at <82d5427af9d84542ac1bab8e50c139c7>:0)
Somehow I think it's related with the screenshot that I have sent in the beginning, I cannot even access
https://hutonggames.fogbugz.com/default.asp?W1181when I want to download the ecosystem package, it says
Hmmm… can't reach this page
It looks like the webpage at
https://raw.githubusercontent.com/jeanfabre/PlayMaker--Ecosystem--Browser/refs/heads/master/Packages/Ecosystem.unitypackage might be having issues, or it may have moved permanently to a new web address.
ERR_ADDRESS_INVALID
If I click on any other package and I try do download from the below link, it works, only when I try to download the ecosystem doesn t work from the page, so I think the issues are related.
