TKL has two issues that we're unable to squash. The "Sorry Dave" message here on the web page, and the maximum level of PC's is now 20 instead of 30. Characters below level 20 will be unaffected, and TKL will be as you remember it. We'll be working around that level limit, by providing items that copy abilities granted by the higher level, and rewards that improve on those.
By all means, if someone reading this has knowledge of how to resolve that last major bug, don't be shy, and let us know the fix. :)
