I've been thinking through all the things that will break in 1.13 and haven't done much about it yet. It comes down to either updating multiple plugins myself (omg pls no) or getting new plugins to replace the broken ones. So instead of trying to figure all of this out on my own, I'm throwing this out to the community. We have outdated plugins and need new ones; what should we use? Prism Prism is our current rollback plugin which hasn't received any updates since April 2016 (well, for bukkit anyway) and uses block ids in its database. Oops. Unless there's a converter from prism to a better plugin, part of switching would involve the loss of all block break data and I don't know the best way to handle that. LWC Oh no! LWC stores block ids too? Fortunately someone has been updating their own version that fixes this issue and adds things like locking armor stands and item frames. Unfortunately this means it won't include the custom changes I made, namely the tiered prices for locks. This list is not final and items will be appended.
