Whenever I choose to withdraw 100% liquidity from a position, the transaction immediately fails. The only solution I found that sometimes works was to withdraw a lesser amount from the position first.

Also had an out of gas error when withdrawing liquidity: https://rinkeby.etherscan.io/tx/0x08c3b02cda3566d3c04bdfd0727ec2ec09739c7c32ed1d251fb8c1d6bcc8abf3
