The solution is already posted before, but I thought it would be handy.
No more scarab problems or dragon problems!
First of all:
Close all Tibia windows.
Step 1:
Download a Tibia.Dat editor.
you can find one at OTFans
just search for:
.dat editor -> [TUTORIAL] Adding New Items to Tibia -> - DatEditor v1.4 by Black Demon
Step 2:
open the Dateditor.
then press File -> Open and search for tibia.dat and tibia.spr
(Normally C:/Program Files/Tibia)
then search for these ID numbers:
2118, 2119, 2120,2121,2122,2123,2124,2125,2126,2127
Step 3:
you will see this:

now delete at all ID numbers the check for Blockspath.
Step 4:
save the tibia.dat and reopen tibia.
