Minecraft Forums

Hello,
I hope someone can help. Any help is very much appreciated. I
So here is the history:
I've been playing on minecraft 1.5.2 for a few weeks and then upgraded to 1.6.1 a few days ago but then started learning about Mods so I downloaded Mo's Creatures. After I downloaded Mo's, I opened Minecraft 1.6.1 and Mo's wasn't there. I opened the older minecraft and Mo's was there so I've been playing on the older one. Today I downloaded MCA and again it installed to the older minecraft so I played with the older minecraft with both MCA and Mo's Mods. After I told my kid to go fishing and minecraft crashed. Here is what the crash file states:

I also have mo' creatures v.5.2.3 mod installed, and MCA v3.3.6, and some others. It's actually installed on an MCPC bukkit server that is crashing for the person that told her daughter to go fish.

will keep googling for now... is there a way to just clear that entity?

Oh, I found another thread on this problem, with a fix! Here:

Posted by WildBamaBoy today (7/6/2013) at 5:27am. I mention that incase you want to verify that link is authentic and not just a trick from me, a noob to the forums :). good luck!

Thank you, feelie75.
I hate to look stupid but what do I do once I download the file. Should I put it in the bin folder?

I'm minecraft challenged but committed to learning.
