Thanks for looking into this and pointing out the specific log sections!
I'd be able to remove farsight and iceberg as well as substituting rei with jei. It's of course not preferable but I'll try this out later and see if it works! I'll report back with the results once I got around to it!
I don't see any reason as to why they shouldn't be. I haven't run into any problems when using them so far but I went and checked their mod pages on curseforge anyways.
Beenfo claims it can be installed on the server for extra functionality, but works as a client side mod.
I don't know why jei is listed there as I don't have it installed. I'm assuming it's rei?
Torohealth doesn't state whether it's client side or not on its mod page, but it is according to comments. Also makes sense as it just displays a hud element that shows the health of an entity when looked at.
GUI clock and compass are client side mods according to the mod page
Panorama doesn't state if it's client side or not, but I highly doubt that it isn't. It just spins the player around when activated to take a panoramic screenshot. I don't see where the server would require anything from what is essentially a macro that takes screenshots and stitches them together.
Durability101 also doesn't state anything but it only displays the durability value of any item over it's durability bar. It doesn't really add anything that the server would need as far as I know.
Collective is the library mod for GUI Clock and Compass.
InventoryHUD claims to be client side only.
Appleskin is mostly client side but gets more accurate if installed onto the server as well according to the mod page.
Not that I'm aware of at least. It seems to be working mostly fine. Though there seems to be an issue where it doesn't save the panorama picture I set for my titlescreen. Maybe that's that? But even then that's a minor issue at best. Still, thanks for pointing that out!
That is true, yeah. Like I stated before the server is running on 41.0.63 as that's the highest version we can go with these mods. Some mods (Like Alcocraft for example) are not compatible with forge 41.0.64+ and we're still waiting for them to update first. So in the meantime we're stuck on 41.0.63 and with it limited as to how far we can update these mods.
