Recurrent Complex runs in compatibility mode when using RTG worldgen, stating: "Chunk finished generating without Forge population being triggered (dimension 0). This is a bug with the dimension - please report this to the dimension's author. Recurrent Complex will proceed to generate in compatibility mode". This limits the structures that Recurrent Complex generates. Tested and occurs on RTG 4.2 snapshots 1 and 3 and Recurrent Complex versions 1.3.2 and 1.4.1. Attached is a server log running RTG snapshot 1 and Recurrent Complex 1.3.2
