[HELP] REGTEST mode Transactions stuck in Mempool?

[stefan123]

I'm trying to mine a segwit transaction in regtest mode but for some reason it just stays stuck in the mempool. To generate my regtest blocks I'm executing the following commands:
 > addr=`bitcoin-cli -regtest getaccountaddress ''`
 > waddr=`bitcoin-cli -regtest addwitnessaddress $addr`
 > bitcoin-cli -regtest generatetoaddress 1 $waddr

If anyone has any idea why this transaction is getting stuck, your help is much appreciated.

This is the transaction in question:

Did you activate segwit yet? Have you mined 288 blocks (IIRC that's the threshold for regtest) to activate segwit?

[stefan123]

Yes, segwit is activated and my blockheight is currently 268. I did start my bitcoin instance with the flags -prematurewitness and -walletprematurewitness but I don't see how that would change anything.
