upgrading blocks from 2016 to 2018 text goes crazy big

[jayrock]

Good morning,

WE have created a standard set of dynamic/annotative blocks for our setup template file as well as to be used in our standards palette. These were created in AutoCAD 2016, but we have come into a problem while upgrading to 2018.

If we save the drawings in 2018 the text in our blocks becomes large and out of scale. This only happens if we save in 2018. Even if we use ATTSYNC and BATTMAN to fix it while working in the drawing the second we save close and reopen the file the text goes crazy again. If we fix the blocks with ATTSYNC or BATTMAN and save down to 2013 the problem is fine as long as we do not open and save in any version newer then 2016. I have not tried it in 2017 as no one in our office is using that version.

Here are some before and after screen grabs.

Does any one have any suggestions.

Thanks.
