After dying when using the Lichtenauer skill on an item that has sweeping edge (which grants Lichtenauer more charges), the visual cap seems to stay at 4 charges. Dying again does not fix this issue. Watch how it goes from its normal 7 charges on a sweeping edge 3 sword, then stays at 4 afterwards: The video was too big to put on github; had to upload to Youtube

It will be fixed in the next update.
