BGII BAM in BG1, game crashes Options

[jastey]

Hi everyone,
I wanted to use the BAM "IPOTN54.BAM" from BGII (inventory picture of an empty bottle) in BG1, saved it under a different name, put it into my mod-installation (.tp2 copying etc.) ... and the (BG1) game crashes when I try to open the inventory if the item (using the BAM) is there, giving me an error message of something in some .bam not readable.

Before I start posting details: Is there anything general I have to consider while transferring BAMs? Anyone has an idea what went wrong?

I can open the item in NI and DLTCEP all right.

Thanks!
