Report a Bug > Contact Support link from within Arena client links to:

Report Conduct selector redirects to:
https://mtgarena-support.wizards.com/hc/en-us/requests/new?ticket_form_id=360000604591

which says:
"To help us solve your issue more quickly, you must be signed in to submit this type of request. Sign In" and there is an identical Sign In link in the upper right next to language selector.

These Sign in links route to:
https://mtgarena-support.wizards.com/hc/en-us/signin?return_to=https%3A%2F%2Fmtgarena-support.wizards.com%2Fhc%2Fen-us%2Frequests%2Fnew%3Fticket_form_id%3D360000604591

(or the similar...)
https://mtgarena-support.wizards.com/hc/en-us/signin

Which is just a search page with categories.
Signing in on a separate browser session, either through this feedback / uservoice login, or through wizards page main login, does not change the Report conduct selector even when manually navigating to https://mtgarena-support.wizards.com/hc/en-us/requests/new in the same session

I need to report about maps not loading properly and sadly this right here explains alot. So I guess everything gets ignored.

I have lots of missing cards that were claimed.

Nothing works with the bug reporting - it just bounces you around until you quit trying - this is what they do they do not care

I can't seem to report a bug about the game getting stuck. The site doesn't seem to explain further as to why my bug could not be submitted.
