Hi,
I am experiencing the same issue as IceComet. installed vidiotmaps and the 2019 maps with no problem. Installed the new maps and got the Sirens call map which is rotated incorrectly.
Copied the newish map_V_PvP_03_01.8badge-i27 map and it displays as a corrupt image (slightly different with a vertical shift each time I use /reloadgfx) with the overlayed items visible (portal, active events, contacts etc)... deleted that and pasted vidiotmap_updates_feb_2021 map (which is about half the file size) and it shows a black/blank map with only the overlayed items visible (portal, active events, contacts etc). I deleted the whole texture library folder and then reinstalled vidiotmaps and the recent updated maps again. Same result-everything fine except sirens call looks corrupt. Then I deleted the whole texture library folder and ran the modder to install the I26 maps, and I get the corrupt looking map again for sirens call.
