Are we no longer using skillbooks? Exhumers missing from NPC stations

Title says it all. Exhumers skillbook is missing from NPC stations. Previously posted about Minmatar and Gallente industrial as missing. Sent a ticket in on that and will make another on this.

may be making folks start buying them directly from the skillsheet

Still not repaired, no longer on sale in school stations. During this time their price explodes on the market.

Buy from skillsheet.

They cost MORE in the skill sheet!! How about fixing the problem. or is that just another way for CCP to extract even MORE money?
