So I got the latest industrialcraft and made an SMP server and client using Minecraft forge, on the minecraft 1.3.2 release with IC2 v1.106. All has been well until now -
jetpacks can't thrust upwards. This only happens in multiplayer - in singleplayer on the same modded client they work fine. What's interesting is that they're not completely broken - they do consume fuel as I hold down the space key, even though I'm just jumping in place, and also, if I put the jetpack in hover mode, It will slow down my fall if i jump off a cliff, as hover mode should. Still can't thrust upwards though. This problem occurs with both electric and chemical-fueled jetpacks.
Here is my server.properties file. I do have allow-fly set to true.
