Unable to see forestry butterflies in multiplayer server, console error spam

[ViruzzzDK]

I am experiencing a weird bug on our multiplayer FTB server. I cannot see the forestry butterfly entities ingame. We are currently running 1.1.3, but I also had the same bug when we were running 1.1.2

I have had errors spamming in the console for a while, I didn't know what they meant until I found out today that they appear every time a butter fly spawned, confirmed and verified with a butterfly spawner, whatever amount of butterflies would spawn at a time would match with the amount of error messages I got.

The error messages in the console look like this:

2013-08-22 16:02:34 [WARNING] [ForgeModLoader] Missing mod entity information for Forestry : 35
2013-08-22 16:02:40 [WARNING] [ForgeModLoader] Missing mod entity information for Forestry : 35
2013-08-22 16:02:40 [WARNING] [ForgeModLoader] Missing mod entity information for Forestry : 35
2013-08-22 16:02:44 [WARNING] [ForgeModLoader] Missing mod entity information for Forestry : 35
2013-08-22 16:02:51 [WARNING] [ForgeModLoader] Missing mod entity information for Forestry : 35

One for every butterfly that spawns.

When I found out that it was butterflies, I tried messing around in singleplayer, and it worked fine there, I can see butterflies, and I don't get the errors at all in the console.

Hope someone can help me with this problem.

Edit: I should mention I have tried completely removing FTB and reinstalling it form scratch, it didn't change anything.

Replacing your client won't do a thing. Try downloading a new FTB server and extracting the forestry.jar from the new one to the old one, and report back (please )

It works for everybody else on the server though. It's just me who's unable to see them.

Edit: I got in touch with a server admin, and he tried replacing it. No luck though, it didn't change anything.
I asked him to delete my .dat file as well (temporarily) seeing as I am the only person having the problem I thought it might be related to that, I still got the error after logging in to the server. So no luck there.

Ah, you could've told me that its only you. It seems then that some server related files are missing from your ftb installation. But, you already mentioned reinstalling. Try it on another server, then on another mod pack in ssp, and then on a different server on the other mod pack.

Edit: try manually downloading forestry.jar. Ftb may be downloading a broken file.

Well good news is it's fixed. Bad news is I have no idea how, so I'm sorry if anybody comes here with the same problem looking for a solution.
I tried some of the servers listed in the server advertising forum, I never found anybody on them nor did I find any butterflies(or see any errors).
After re-downloading new versions over and over again I ended up back on our own server and I could all of a sudden see butterflies.

I have re-downloaded the pack several times though, and the only thing I can imagine was different this time is that I forced the launcher to use a mirror that a friend of mine on the same server told me he used. I am from Europe so I probably had it set to one of the England mirrors. Maybe one of the England mirrors has a slightly corrupt version? Or maybe It just got fixed through dumb luck, I don't know.

It may be, but I also live in europe, (England) And I don't find any corruption in any files. Strange
