Uhm.. Nope, no problems with texture packs at this moment. Well, you always can do some changes, people just revert back if something goes wrong. I'm always do general backup of mc before update something.
About uploading maps: i could do it right now, but, big but - it is a multiplayer map, this map uses plenty of mods (full of mod blocks), server used in OS X (Apple's OS) environment. So, for those who want it - just answer me, are still need it or no? If yes, i will upload in next 1-3 days.
