Mobs not spawning correctly after using custom build

I got sold on a custom build of Bukkit called CraftBukkit++ by Afforess . I tried for a few days but then uninstalled it (nothing wrong with it; the side effects just aren't worth it for a small server like mine). After I uninstalled it, however, I started noticing several things:

(Just to clarify: the following effects happen on the standard Bukkit R4 build.)

• Animals seem to be spawning naturally again in certain areas (but not everywhere), like they did pre-1.8.
• A lot of times, whenever a player logs in, they are surrounded by hostile mobs no matter where they are, what time of day it is, or whether there were mobs around when they logged out. It happened to me twice personally - a creeper blew up as soon as I logged in and when I came back to my death spot I had like a dozen zombies and spiders around me... burning up by sunlight even though it was the middle of day.
• Two players have complained that their mob grinders aren't spawning any mobs. One player said it started working fine after a while but then it stopped again. This seems to me like a "mob cap" feature like what CB++ had but I'm not running it anymore. The NoLagg plugin also has a mob cap feature but I'm not running it anymore, and I never had mob capping enabled when I did run it. Nor did I ever have any similar problems with NoLagg or during the weeks after I uninstalled it.
• SOME tamed wolves are broken. A player right clicks them to make them stand up but then they either teleport to god knows where, and if they stay then they do not follow the player and just walk around the area they were at. This only applies to some wolves; others work fine.

This is really scary because I haven't installed anything new except CB++ which I only ran for about a day. I thought the effects would get fixed by now (as players re-visit chunks) but it's been 3 days and stuff is still happening. HELP ME!Here's a full list of plugins I have:

No one? Aww come on! You guys are smart! I'm gonna go play process of elimination with the first issue I mentioned and see what happens...

 

Please post what you find! I'm having the same issue. Animals started spawning again but monsters now do not spawn. Using Bukkit-R4

 

Bukkit does not support these unofficial builds
