[FTB Beyond 1.10.0] Crash when teleporting block

[Hexus-One]

Hello!

Playing on a friend's server but I have remote access to the machine. I have a simple setup with two Frame Teleporters; both are directly powered with Flux Points and both have stone buttons mounted on them. Both are also facing straight up. I've placed cobblestone on top of one teleporter, pressed the button and then my client crashed. The crash message I get is

Internal Exception: io.netty.handler.codec.DecoderException: java.lang.RuntimeException: Tried to read NBT tag with too high complexity, depth > 512

On the server console I get

[16:32:44] [Netty Server IO #0/DEBUG] [extrautils2/]: OTL: Decode Packet: com.rwtema.extrautils2.network.packets.PacketUseItemAlt [16:32:44] [Netty Server IO #0/DEBUG] [extrautils2/]: OTL: Handle Packet: com.rwtema.extrautils2.network.packets.PacketUseItemAlt : SERVER [16:32:44] [Netty Server IO #0/DEBUG] [extrautils2/]: OTL: Scheduling Packet: com.rwtema.extrautils2.network.packets.PacketUseItemAlt : SERVER

I'm able to safely rejoin and repeat the process with no apparent permanent effect to the server.

Edit: the crash also happens with other frame blocks :C

Edit: The blocks actually do successfully move, just that for whatever reason it crashes the client.
