suggestions

Any way to update it so you can't click "fight level x" and there is no one at that level.

When you get higher up there are many levels that have no one at that level, so make it show only the levels there are people at.

(not very clear so here is example)

Level 150,151,153,154,160

Since there are no bots at level 152,155,156,157,158,159, you don't see it

I'd prefer the numbers for the levels with no bots are greyed out/unclickable rather than not being there, for the sake of continuity.

still +1

^^ something like that

Yes, grey the level link out

Yes +1

greyed out sounds good.

Done.
