Hi @heiisniper,
Thank you for your bug report regarding card “53021” interacting with “50014” in version 0.5.9.188. We were able to reproduce the issue following your steps.
The crash occurs because the game does not properly handle resource cards with interrupt effects, like “50014,” when used with “53021.” For the current version, please avoid tucking this type of resource card under “53021.”
We will address this bug in the next version. Thank you again for your valuable feedback!
