What gameplay feature is this bug affecting?
battling, event shop

What's the issue? Please include any error messages you receive and as much detail as possible.
Whenever I almost defeat rabid kudu in explore on lioden the page glitches and I can't finish the fight.
I also can't buy Devil's Claw, because as soon as I'll click "buy" I get the error saying that page is not working.
That's really inconvinient, since if my lion will get rabies and hurt the pride, I can't do anything about it, and I can't really attack any rabid animals in the event, losing the chance to earn Blood Beetles.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
https://www.lioden.com/halloween.php - that's the address of page that says "the page is not working"

Any screenshots you can provide us with?
I may send some over when it happens again, I didn't made a screenshot because I didn't knew it would be needed and I don't have any energy for now to make it

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
1. I went to the explore, I saw a battle with rabid kudu option. I've clicked "attack", and them almost killed it (it hardly had any hp). as soon as I was about to make a final attack and win, I got the communicate that I need to click any link on the page because something went wrong, and then when I go back the battle is invalid and I can't go back to it.

2. When I go to the event store, click on devil's claw, select the amount and click "buy", I get the popout asking if I'm sure I want to buy it. When I click "yes", the error occures, saying that the page is not working.
