13 Word backup restore (reddit.com)

I added a few dollars to a bitcoin wallet and created a 13 word backup roughly a year ago. Since then the phone I was using broke and I need to restore. However when I go to restore it in either Mycelium or Electrum it won’t accept 13 words. Mycelium stops at 12 and Electrum waits for another. I haven’t used it since adding the coins and I forget how I created it in the first place. My question is, how can I restore my backup?

Why cannot malicious miners award themselves with any number of bitcoins?

I’m new to the topic, so if my question doesn’t meet the question format requirements, please notify kindly and I will change it accordingly. Thank you.

My question is, why cannot malicious miners award themselves with any number of bitcoins? Is that because the award itself is a transaction which has to be confirmed by a random miner? And if so, what if the miner himself will win the race?

Also, why cannot one “pretend” to having solved the block and broadcast self-award transaction any time I want?

Also, if award is a transaction, who is the sender?
