Your Actions

Adding Dynamic+Lights-1.3.9a-MC1.7.10 makes it impossible for a client to connect to a server. Neither the client nor the server crashes, but the connection is broken as soon as it is established. The few seconds of log from fml-client-latest is as below.

The mod was only added to the client side, as adding it to the server prevented server startup.

The only other modification to the game is the addition of the non-fairplay version of journeymap, installed according to guidance on the wiki by removing both jars on server and client, then only adding the non-fairplay jar to client side.

The issue resolves itself as soon as dynamic lights is removed from the client.

If relevant, the client is an M2 Mac.
