I have recently updated to the 1.9.4 forge server and can confirm with no other mods installed and running unmodded forge server the latest forge to work without invisible zombies was forge-1.9.4-12.17.0.1941-universal
However this version has issues as it looks like mobs dont drop items like meat or hide.. this is unmodded forge. It took me at least two hours to find one that the zombies were not invisible.
the latest one I tried was "forge-1.9.4-12.17.0.1963-universal" and the problem is still previlent.
If i try and run optifine i get the following It crashes out as well with the following error
---- Minecraft Crash Report ----
// Surprise! Haha. Well, this is awkward.

however on version forge-1.9.4-12.17.0.1941-universal optifine works fine I have tried google search to try and find a fix and cant find one. I am hoping I am not the only one with the issue.
Thank you for your time.
