Missing mod entity information

[Torojima]

one of my players has some problems with my mods entities. They are not shown in SMP mode. But as he states only in his client. Other clients connected to the server can see the entities.

 

The only irregularity I've found in his client log are the following two lines for multiple entity id's

2013-06-08 12:43:50 [WARNING] [ForgeModLoader] Missing mod entity information for chococraft : 5
2013-06-08 12:43:50 [FINE] [ForgeModLoader] Attempted to adjust the position of entity 55321 which is not present on the client

 

can somebody enlighten me and tell me what the two lines (especially the first one) can tell me?

It's his problem. Most likely has some irregularity in his file; he should re-download it.
