A simple plugin to make blocks expire after 20 seconds. If I see this plugin being used a lot I’ll add a configuration for customizable time. This uses NMS so it’s only compatible with 1.8.8, but again, if this plugin gets used quite a bit I’ll make it compatible with other versions (probably by removing the unnecessary use of NMS). If you have any contributions to make, feel free to submit a pull request and I’ll be sure to review it!
