ticking entity java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Float

I'm recently getting this error whenever i try placing any rolling stock - be it locomotives, freight wagons or passenger carriages - freezing and then crashing the client but not the server, which does not throw any error at all. Then, any player rendering the chunk where the rolling stock was being placed also crashes. I have to remove the entity and tile ticks with mcedit in order for anyone within rendering range of that rolling stock to be able to join again without crashing.

Weird thing is that rolling stock could be placed without error in the beginning, but this issue came up without any apparant cause and now affects the entire world.

Here's the full crash report.

Afther further testing, Even removing the mod and the TrackAPI dependency, rendering the entire world so all the blocks are cleared, and re-adding the mod does not fix this issue and still makes the client crash when placing rolling stock.

In fact, once i added the mod back in all the track blocks that i thought were removed from the world got back in as invisible slabs (the 3d track models themselves were not rendered) causing the mod to output "[Server thread/WARN] [immersiverailroading]: Invalid block without parent" to the server console a few hundred times or so at once. I was able to track and remove those invisible blocks thanks to Rei's minimap and Worldedit, otherwise it would have been very hard if not impossible to get all of them cleared.

Lastly, i was able to get some additional information about the circumstances when this issue started appearing. This was when one of the diesel locs (the one with max 105 km/h, can't remember the name) ran off the end of a railway line under construction and froze there, unable to move forwards or backwards. When the player shift + left-clicked the loc to retrieve it into an item is when the client first crashed and when this issue started.

Since i cannot resolve this issue, i will run the server without this mod for now. If you would like to take a look at a copy of the world (or the entire server, which is 1.46gb) i have a copy saved which i can share with you.

That's really strange, I'll take a look tomorrow

Okay, final update. I got this issue resolved for me personally.

i placed a locomotive on a track, on the 'real' world map, and the client crashed as expected.

I then deleted the scheduled tile ticks, NOT the entity in mcedit, and then restarted the server. Upon logging back in, my client did not crash and i saw the locomotive i placed attempt moving on the track but constantly being teleported back to it's starting position. I retrieved the locomotive with shift+left click and it was retrieved successfully.

Since i've performed this action, everything runs as normal again. I was just able to place a bunch of locomotives without any issues, drive them around and retrieve them into item form again.

I can only imagine that the locomotive stuck at the end of a suspended track, unable to move and crashing the client upon trying to retrieve it into item form somehow caused this issue. i wonder how this could possibly cause a type casting error to be thrown upon rolling stock placement though.

That said, the issue has been fixed for me personally. I still have a copy of the world around where this issue exists, if you'd like to use it for testing.

Upon further testing, it looks like this issue is isolated to the specific world. I copied the server, deleted the world and had a new one generated and that 'fixed' the issue.

I'd really rather not lose the world i currently have. Is there any way i might clear data that ImmersiveRailroading left behind in that world?
