Skills disappear from hot bar when attribute requirement is from megalomaniac

I have the passive 'Lucidity' allocated from the megalomaniac jewel which provides 15 int. With this I'm just over the 157 int requirement for my ball lightning and arc gems.

Switching maps or relogging will remove those two skills from my skill hot bar. If I then allocate enough int so that without the 15 int I'm still over the 157 int requirement then this issue no longer occurs.
