While this is an incompatibility with an alpha version of Scape and run: parasites, how the biome is generated will likely not be changing. Before testing this, read the alpha changelog, as it will explain how the biome is generated, and how some mechanics work. The issue is the nodes do not generate the infested plains biome - if you need any help finding this issue, please let me know.

Confirmed: tested with and without JEID.

JEID causes Nodes to lag the server, booting even those in singleplayer. Causes massive tick lag, and the biome doesn't actually spread.

Expect result: Nodes do not lag the server, and the biome spreads normally.

Tested with SRP 1.9.0, Alpha 2, latest version of JEID.

Proposed workaround: Maybe nodes will work with Not Enough IDs?

Edit: additionally, no crash log is dropped, only a stall log. Hm.

Update: Error caught live in Miami:

Go wild. Either mod and it's developers can use this. Using any JEID version with the biome ID extender will report this.

Opening to LAN reveals just how laggy this incompatibility is, besides just not letting the biome spread. This log snippet shows me getting kicked out of my own LAN server because the SRPPacketBiomeChange packets caused a massive memory leak, frame stutters, and eventually death of the server.

Please prioritize this issue.
