How did You solve it? I have the exact same problem:Hey Marko,
I can't open your items.otb, neither the .spr or .dat in any type of editor.
The weird thing is, the sprites work in my tibia server.
I tried using items editor, lapis editor and got not luck with the items.otb.
In Item editor, I get a message about client version 64, when using your Tibia.dat, Tibia.spr with your items.otb:

Lapis editor does not even output anything useful, it just stays stuck in Loading graphics forever.
Then, when I try to open your .spr and .dat in the object builder. When selecting the file, the signature and the sprites show up looking like they are loading:

However, when I try to open the file, it logs the following error:
View attachment 95465
I'm using Object Builder version 0.5.5.
I must say I'm stuck, because I can't inspect any of the items and I need to inspect somehow which items are included, otherwise it is not possible to switch some of the sprites that are wrong in my items.xml and in the tiles.
EDIT:
Looks like I have the same error from object builder in the item editor:

OTB version 64.
PluginThree: Error while parsing, unknown flag 0x85 at id 100.
Failed to load dat.
Loading client files.
Client version 860.
How did You solve it? I have the exact same problem:
I can open spr/dat from 860-cip branch just fine... what im missing? I noticed .dat from main branch is bigger
If you are using main branch, you have to enable the features in itemeditor
RME 3.7, data/clients.xmlNOTE: To avoid problems with map saving make sure to change in your rme files under data/clients.xml
from otb client="8.60" version="3" id="20" to otb client="8.60" version="3" id="64"
To avoid bugs and problems Create a blank map and then import your old map on itThat's it.

Have you already placed the .dat and .spr files on the client?Hi again, I followed instructions on github:
RME 3.7, data/clients.xml
<otb client="8.60" version="3" id="64"/>
OTClient
copied .spr and .dat to data\things\860 <- This is the .spr/.dat file i pointed RME 860 to
Copied items.otb and items.xml to RME 3.7\data\860
But when i open the imported map it looks like this:

Somehow the imported map isnt openning anymore on RME, it loads but then rme exits without error everytime... tried 2.2, 3.7. 4.x, 4.1.2 (otacademy) but same thing happens... No error shows up, any clues?
Thx

perhaps you can just change yours to the version you need here in the item editor? not sure all the details but maybe this will help ^^
TFS 0.4 or based on tfs 0.4? I tested it on TFS 0.4 and it worked
