There's been a long time of using a l2jfrozen one because I thought it would be very good for the type of server I wanted to know, functional Grand Bosses, Olympiads working well, class balance system, good mods added, but mainly, I found a lot of content from people who use frozen on the internet which helped me a lot to learn how to compile adding mods by eclipse you know. Well but lately I have really found some problems in the current frozens like 1001, 1004, 1118, 1132 that I can't fix, and I went back to an older one trying to escape from such problems, it improved a little, but even so in some sieges or skills I find some bugs.
